How to spend my next $1k or $2k??? - a little help please.

As a little intro: I shoot mostly hockey games, vacations, buildings, and hiking. I have been reasonably happy with what I have and have managed to get some photos that I'm really happy with over the years. However, most of my equipment is starting to age and I'm thinking it's time to add to the fleet or upgrade. The problem is I'm not made of money and my wish list is longer than my checkbook so I'm wondering where to put my next investment.

So this is what I have:
Rebel XT D350 with grip (It's just too small without the grip) (slight edit to add D350 and 8MP, CF memory, 3 fps shooting)
EF-S 17-85 IS USM
EF 50 1.8
Sigma 70-200 2.8 USM (Very old one without OS or Macro)
Sigma 2x extender

What I'm thinking about:
EF-S 10-22 (Something new that would give me a perspective I don't have)
60D (Higher ISO, better images, faster burst rate, video)
EF 70-200 IS (Image stabilization, this might be outside the budget)

I have also had on the list and although not excluded they have fallen to the still in the hunt category:
EF-S 17-55 2.8 (Faster but shorter than what I have)
EF-S 15-85 (very nice, but almost on top of what I have)
EF 28 1.8 (Seems like something I might pick up later, or possibly the 2.8 IS)
EF 24-105 4.0 L (I just don't know)
7D (Very nice, but do I want to spend the extra over the 60D)

I'm also open to suggestions of other options. I just was hoping to talk this one out loud.
