I'm more or less at the same point myself, although I don't really care about loot. I'll work up to the best available, but so long as gear level isn't keeping me from content, I don't really care what I'm wearing.

What I care about is progressing the story. Once I clear out Icecrown, I'm more or less out of things to do. I can farm Gold, heroics, raids, etc, but truth be told, farming and whacking the loot pinata gets old real quickly, especially when the loot pinata only gets refreshed once a week. As it stands, I have, at best, a few more weeks of play time before I cancel my accounts and find something else to do.

Of course, Ulduar gets released in a few weeks, but still, all I see out of it is more raiding and a new arena season, which is fine, but since I don't really care about either, its a meaningless patch for me.
