The Guarded compund in the Temple district should give you some nice exp and items.
There are two hidden enemy parties in the Bridge district, first one is behind a door in the alley between the Five flagons inn and the Fallen paladins hideout, second one is a mercenary pack on the second floor of the inn after the Tanner shop. Both parties should net you about 30k exp each.

Also, maybe you're not mentioning these because you take them for granted, but I noticed that neither the Slaver quests nor the Circus quest in the Slums & Promenade are on your list, doing those quests will give you good exp.
