My goal is to upgrade to the full frame in a year or so...I'm going to take a serious look at this 17-55mm f/2.8 , a lot of people have mentioned it....I'm hoping for the 70-200mm f/2.8 II USM really soon ! Thanks for all the help.
Personally, I think the 17-55mm f/2.8 IS is the best general purpose zoom for a crop body. I kept mine when I added a 5DII to my kit, since I still have the 7D and want a general purpose lens for when I go out shooting birds/wildlife with the 7D+100-400mm.
I do believe that you should get the lenses you need/want today, regardless of plans to go FF at some point. Many who planned to do so are now on their second or third crop body!
The 70-200mm f/2.8L IS II is a wonderful lens, but FWIW I have found it a lot more useful on FF than on 1.6x. With the 7D, the focal length equivalent is 112-320mm - for me, that was too long indoors but not long enough outdoors (since I also had the 100-400mm). On a crop body, I found the 70-200 II most useful for outdoor event shooting (backyard parties, at the beach, etc.). Now, on the 5DII, it's a wonderful outdoor and indoor lens and sees a lot more use.
