The only major thing that spring to mind about your equipment is the weapons. I dont have the stats to hand, but it may be worth putting the katana in the main hand. Remember the main hand gets more hits. But thats just a guess, as I say I dont have the stats on the Acid Katana.

on the spellbook question, in general, you should memorise all of scrolls you can find, for XP. The only concern is that you may run out of spellbook slots if you dont have a high enough INT, but if oyu have ToB installed you can delete spells so thats not a major hassle.

However, with a F/M/T party character, I wouldnt think your going to be able to cast 9th level spells anytime soon, so hand those over to, hey, you dont have a full mage? Unless its Kivan. Anyway, if its a spell your not going to be able to cast from spellbook in a long while, it may be worth keeping it to cast from scroll.
