Swashbuckler (CW), perhaps? You'd have Weapon Finesse, flashy skills, and you'd add Int to damage after a few levels. Dip a level of Ranger to get Track (making you more useful out of combat) while still keeping a full BAB. Add a second level of ranger if you plan on going the TWF route, which you might as well since you can't use Power Attack.
Complete Scoundrel has some nifty goodies you might want to look into.
