I might also consider a Ranger dip- esp. an Urban Ranger- and concentrate on ranged combat instead of 2WF.
You've got the Dex and the racial bonus- use those daggers, clubs, shortspears, spears, darts, javelins, throwing axes, light hammers, tridents, shuriken, nets, thunderstones, alchemist fire, tanglefoot bags, etc. and stay out of combat! (Try hard to find a Quiver of Ehlonna.)
You have some decent skill synergy and you wouldn't lose many skill points.
If you dip far enough into Ranger, you can get a riding dog as your animal companion and further boost your movement rate...don't forget mounted combat feats! OR you could get a dire rat or one of the flying animal companions and train it to steal things for you. (Yes, I know Handle Animal is a Cha based skill.)
