At our high school gym I can take a decent picture, it has good light, at the middle school gym, I may as well not get the camera out of the bag, it's dark.
Yes, timing is everything. Thats the good thing about shooting digital, make adjustments, anticipate the next play.
A 1.8, 2.8 lens is the lens for dark gyms. Saving up right now.
All the above info is great for you but I would add one little extra. My son-in-law has a canon Xsi and the kit lens is pretty good. Probably the best kit lens around.He has also shot at ISO 800 with very acceptable results. ISO 800 should give you a fair amount of shutter speed even in low light gym's. Also would suggest you come off Auto and use the "Sports" setting. That is biased towards higher shutter speed and will let you catch the action.
