Do all the quests in the city. Except the Twisted Rune, Guarded Compound, and Kangaxx's Body Parts. That should give you a good bit of money, and you will have allies for the fight with Bodhi afterwards. (Drizzt, Radiant Heart, and Shadow Thieves)
Take LOTS of scrolls with you to Brynnlaw. When Imoen joins your group, she will be very lacking on spells. Scribing 20+ spells will help her level up, too.
