You could also consider Knights of the Throzen Throne if you're willing to move one zone down from Icecrown to Dragonblight. Though that's just an idea since I do think the others might be more interesting.
As for my class, I'm currently between Mean Streets of Gadgetzan and Saviors of Uldum. The prior would fit into the outlaw theme, especially since my class is based partially in Tanaris and by extension Gadgetzan, one of my basic cards is even called Gadgetzan Bodyguard. Saviors of Uldum would also work since my class was only -partially- based in Tanaris. The other 2-3 zones I considered to expand it to are Uldum, Vol'dun and Westfall.
