Artemis.....you can find a great club later on (+3 and another +2 which is +3 vs undead) but let me know if you want to be spoiled about their location. I totally agree with Memny that that spoil was totally uncalled for! Hope you managed to avert your eyes in time...
My tips:
KEEP JAHEIRA!!! She totally rules! I have her with an AC of -7 wielding a spear +3 or alternatively with an AC of -11 (!) wielding a club +3 Plus the Insect spells are just SO useful!
I'd ditch Nalia if I were you...if you're not against using evil guys, you could use Edwin (very good mage) but he doesn't work well with Minsc. Try Jan Janssen so you'll have a decent thief/mage and some great conversation.
