Hey there Deus,
Glad you're enjoying the shard so far!
Okay, let's break this down into some chunks for ease of reading, and hopefully i can provide you some insight on where to go from here.
First things first, (i'm a realist... Ok no, i'm sorry i'll stop)
You've gotten off to a great start, but there are still a LOT of skills that you should attempt to raise because they will greatly help you.
Skills to 120:
Necro/Spirit Speak: Using Vampiric Embrace and Curse Weapon are quite helpful for survival, and Wraith Form/Wither are great for weaker champ spawns. Plus Spirit Speak is the required skill for the Cleric spells one you get that spellbook (Which i highly recommend)
Chivalry: This is a MUST. Consecrate Weapon, Divine Fury, Remove Curse, and even Sacred Journey are wonderful spells to have access to.
Bushido: Now that there is no penalty to having Bushido while wearing a shield, its abilities are a huge benefit. Confidence heals you and restores stamina on a successful parry, Evasion allows you to take no hits for a short period of time (with a long cooldown), Lightning Strike is a low mana alternative to weapon skills and has a chance to perform armor ignore (For only 3 mana).
Hiding: Getting to 120 hiding (Requires a powerskull, 120 hiding scroll does not drop natively in game) will allow you to instantly hide and drop aggro even in the midst of combat. it is an absolute godsend.
I'm pretty sure you have them already but Anatomy/Healing/Tactics are quite important as well.
Next on the list, Let's talk about your Weapons and Gear.
You have a good start with the Astro Daemon/Fortune gear. Now you just need to start looking at higher levels of gear. it is a big leap between that set of gear and the next tier, but to paraphrase something Kane and Dante have said repeatedly, this shard is not a sprint, it is a marathon. You merely have to start obtaining incremental bonuses and working your way forward.
For your weapon, I would not be able to advise you to invest in it without knowing the exact stats. You really want an axe that has 40+ Triple Leech (Life, Mana and Stamina) and one hit spell (Preferably Fireball or Lightning) at 40+ when it is crafted. The hit spell is not technically required, but the axe will be much better once it is completed. I also wouldn't focus on getting a Bow until your first axe is completed, as you will do decently with a Lightning Bolt or Ice Cross Power (PM me in game if you do not have one of those. I'm sure i can find one in my Vaults 
).
As for the Pet questions, I do not personally use pets because i don't enjoy the playstyle (I can barely keep track of myself much less pets) however, from my research it doesn't seem to benefit you until you can get enough pet slots to add another 2 or 3 slot pet to your team. (there are some people who run with all Frenzied Ostards who disagree with me there.) If you only have 5 slots now, and want to run both AFS, then a 6th slot is probably a good idea.
For gear, things to work toward would be things that fit your playstyle, Are you going full tamer? Dexxer?
There are a lot of very nice pieces of gear such as the Kas Armor for Dexxers, I personally use the Kas Gloves, Magi Arms, Magi Chest (Male), Royal Guard Legs, I have some Event items as gear as well. Monthly events are great places to gear up as a bridge to Veteran status. Take a look at what people are wearing around Brit Bank and things, it'll give you at least an idea of what to look for. I would suggest speaking directly to a Vet in game before making any large purchases.
As for collecting Parry Augs, it will take a while to do so, i have been playing for ~6 months and i've gotten one from a drop. Luckily, you have a ways to go before you really start socketing your gear, I'm fairly sure i only have 3 pieces socketed with Parry so far. Defnitely collect any Augments you find and hoard them like a dragon. They will come in QUITE handy later once you start getting higher tier gear.
I have a few questions for you as well,
What is your current stat cap? (What level of stat scroll have you eaten)
What type of character/playstyle are you going for?
Now for your final question, you asked what the best way to make gold was, and the answer to that is: There really isnt a "best" way.
You can do lots of different things, I really enjoy running T-maps, you get lots of gold from the spawn, and lots of reagents/scrolls/gems from the chests. Champ spawns are also a nice way to make gold, but are a bit more difficult for beginning players (The undead stadium in Malas is nice as long as you can handle it, and drops a TON of magery/necro reagents)
SoSs can bring in a decent amount of money and Magical Cloth Deeds/Weapon level scrolls for you to use or sell.
Mining and Lumberjacking can be profitable if you sell your farmed materials.
Farming Dungeons as Sturger suggested is also viable, Stygian Abyss, Sorcerer's, Wisp, the Bio dungeon (which i believe is near Ankh in Ilshenar) all of these are decent amounts of gold.
Other things you can do for gold is farm up the monthly event items, and the extras you get or the things you dont want, sell them to other players. Our server has a pretty vibrant economy, and players are always looking for things. You can sell almost anything to the right player. Especially things like semi-rare Deco items, and things like that.
Make sure you participate in the staff events too, Joker, Expo, Domino, Kane and Dante all run events near constantly, and even if you dont win there's usually a participation prize (except in the case of the Champ spawns, where the prizes are the scrolls) but those all add up as well.
Anyway this turned into an excessively long post, I hope it helps!
If you need anything feel free to ask here or PM me in game i will always respond when i can

I have 100 Necromacy and 110 Spirit Speak
Chivalry: This is a MUST. Consecrate Weapon, Divine Fury, Remove Curse, and even Sacred Journey are wonderful spells to have access to.
I have 105 Chivalry and for monster who need a large number of hit i maintain CW and DF and Enemy of One
Bushido: Now that there is no penalty to having Bushido while wearing a shield, its abilities are a huge benefit. Confidence heals you and restores stamina on a successful parry, Evasion allows you to take no hits for a short period of time (with a long cooldown), Lightning Strike is a low mana alternative to weapon skills and has a chance to perform armor ignore (For only 3 mana).
Bushido is only at 100
Hiding: Getting to 120 hiding (Requires a powerskull, 120 hiding scroll does not drop natively in game) will allow you to instantly hide and drop aggro even in the midst of combat. it is an absolute godsend.

I have only 100hiding and 115 on tattics anatomy and Healing.. for combat skill i 115 sword and 120 parry

You merely have to start obtaining incremental bonuses and working your way forward.
What is the next piece of gear i need to search for buy? i don't want spend a lot of milion for useless gear or for a very minor upgrade

I'm sure i can find one in my Vaults
I Don't have a bow, i use Zeldasword when pet tank for the high output damage, the tomb raider scimitar for heal me for swarm monster (i have spend some self repair deed for not broke that) and the Axe is 2h for now and have:
Damage Increase 58%
Defence Chance 15%
Faster Caster 1
HLL 46
HML 50
HSL 48
Hit Lower Defence 50
Hit lower Attack 4
Hit Lightning 2%
Self Repair 5 (added with deed)
I need to find scroll for a +40poison area and +25firearea

For gear, things to work toward would be things that fit your playstyle, Are you going full tamer? Dexxer?
For my Personal UO experience my playstile is play like a warrior, a few usefull cast and melee attack, if supported by pet is good for me
