What are some good lens for the Canon Eos Rebel Xsi / Canon 450D?

I'm really not a fan of the lens, the kit comes with, so I was wondering what lens to buy. I most likely to use this camera for action shots and general use.I'm still a beginner, so help me out here.

I'm using Canon 20D. I would recommend Tamron 17-50mm f2.8 lens as a walk. It is a very strong lens, which will f2.8 and at a fraction of its counterpart Canon EF-S 17-55mm f2.8. A telephoto zoom Canon 55-250 IS would be, but the main problem with this goal is the reproduction of color is a bit sad, gray tones in it. Well, I guess you get what you pay. I used an old Canon lens f2.8 80-200L and I'm addicted to it. Charming!
