nice to see some more cheerleading here. Is that Cheer Athletics? Faster glass is a must! As others said before, the lighting can be very tough to deal with. Try to nail the peaks and also WB in camera. Saves alot of headaches and time with less PP.
I shot some myself this weekend (daughter competed at Jamfest in Indy, but I haven't even pulled the cards out of the camera yet!) I will get some up soon.
As far as carrying the laptop with you....yes, it can get heavy. I had my bag full all weekend and will not do that again! ( Macbook pro 17", 1D MK III, Xsi, 100mm, 70-200 2.8 IS, 50mm 1.8 and all the cables and misc. stuff to go along with it all packed in my bag all weekend.... next time I will bring the roller bag!)
Keep shooting and posting!
