I would not suggest people use their Skill Ball at all. there are a lot of skills that are impossible to gain without one. (Such as hiding past 100, throwing for non gargoyles etc.) Also, Bushido is not recommended if you will be wearing a shield. the penalty to parry while wearing a shield is far too great.
Champ axes are quite nice, and very important to getting stronger. Ask a veteran player for tips, and check out this guide http://uoevolution.com/wiki/index.php/Weapon_Crafting_Guide
Luck isn't worth it until you can get it on your actual killing gear (With the exception of a luck suit for digging up T-Maps and SoSs) because it will hinder your abilities far too much.
Artifacts will drop more often if you have luck, but most of the "Good" artifacts are from Quests (Such as the Kas quest and Magi quest) and from higher level bosses (Like Champions of Champ Spawns and Stygian Dragon etc.)
The lootbag is best used for things like regs/materials and bulk items that stack like gems. Autoloot is better for things like Augments/Quest Items (Such as the monthly quest items that specifically do not work with "Claim") There is also a program called CLAW (a script for EasyUO) that you can set rules in to loot jewelry/items (Such as looting every piece of geat that has +10 or greater skill, or even to the point of looting a ring that has +10Taming/+10Lore/1FC/1FCR/50+luck It's quite powerful). (I have noticed it argues with the autoloot setting in SteamUO however, so it's better off one or the other.)
The other tips i'd have for figuring out what gear you want, is to figure out the playstyle you want? Do you want to be a dexxer? getting up close with a double axe and wrecking face? Do you want to be a mage? (Mages are generally better for PvP than PvM) Or do you want to be a tamer and rely on your pets to tank and do most of your damage?
Once you have that figured out take a look at the gear of people hanging around brit bank, see what they're wearing and try to figure out why. Look into the augments/sockets. learn what you can and cannot socket in the way of stats and gear. and what items are and are not socketable.
Hopefully this helps you move forward.
