I actually used a paladin in BG1. They are cool as hell!! (Oh, and wait until you get the Holy Avenger.. HOLY SH**!!!!!!!) Also, unless you like the headaches of losing fights and reloading, I would save off on these quests (in order of difficulty) until higher level because in chapters 3-6 you get TONS of quest experience (I was leveling once an hour in every chapter after 3rd): the red dragon quest; Slaver quest in the temple district; Twisted Rune Tower (VERY TOUGH!!!); any of the lich battles, ESPECIALLY kangaxx.
Also, beholders throw rays at you, they are not spells. That simply means they cannot be disrupted, which sucks. And remember to always ahve LOTS of ruby rays, pierce shields, breachs, and the like.
eh, i'll procrastinate later...
