canon 5d markII - full frame sensor, legit camera. Little pricer though and only 3.9 fps. -$2500
OR
Canon 7d - 8.0 fps, great for sports, weather sealed body, 1.6 crop factor could be a bonus for telephoto shots. Great price too. Probably your best bet. -$1500
Canon 70-200 f/4 L IS - $800. Must have for sports imo, and the f/4 has been said to be sharper than the 2.8, and you won't need the 2.8 anyways IMO.
Canon 50 f/1.4 - $300. Standard lens, crisp, great quality and a must have. Great low light as well.
Tokina 11-16 f/2.8 - $600. This is probably my favorite lens ever. So crisp, so wide, an awesome must have. works only with the 1.6x aps-c sensors, but the 7d is a great camera for action photog anyways.
Battery grips, batteries, etc - $100.
