does this server have the lrc outfits ?
if youi can get a full lrc suit(lower regeant cost) you won't have to worry about regeants.
you can only case a certain amount of spells based on your skill if you are a nwe char you can't cast ress yet you can probably only cast up to lvl 4 or 5 spells.

You don't gain levels in uo it's all skill based Stratis has some good guides on how to raise your skills
