j elky, you have a couple things that are working slightly against you. You need speed to stop action which Fair Chase has pointed out. With the T2i, the sensor may get "noisy" or grainy when you push the ISO. Short of replacing the camera body, it can't be avoided but you can use it to your advantage. You could shoot as BW and it would just look grainy, no big deal. The kit lens you are using is probably about an f5.6 at 55mm. One thing you could look at is to pick up a good fast lens, like the Tamron 17-50mm f2.8 which will give you more light hitting the sensor and you could shoot at a lower ISO and reduce noise.
You might be able to pick up a newer body with newer sensor technology for your budget as an alternative. I would call up to Camera Land to check options and see if any of them work for you budget and requirements. Talk with Mark or Joel and make sure you let them know you are a member of the Campfire.
