you need to open up the Argent Crusade and Ebon Blade rep lines. The Ebon Blade has 5 boxer friendly and one boxer non-friendly dailies which give XP every time until you are 80.
The Argent Crusade cannoneer trinkets are usually pretty nice, you get them from one of the latter quests there.

Icecrown can be a be-och to move around in though, lots of phasing which usually has me cussing like a sailor, but the quests are still pretty good.
