Get Clear Shots
You're going to want to isolate your subjects from their backgrounds, and capture them as shaply as possible (unless you're going for some artsy effect, but I'm not good enough to do that). To do so, shoot with the lowest f-stop (i.e., the widest aperture) that your camera or lens is capable of, and the fastest shutter speed that you can use and still let enough light into your lens to convey a image.
In general, the wider the aperture, the shallower your camera's depth of field - depth of field being the distance in front of and behind the in-focus subject that remains in focus. Now, "shallow" may sound like a bad thing, but if you're trying to isolate a subject from her background, you want the subject in focus and the background blurry. The following image wouldn't have highlighted the ball-carrier had all the players been in sharp focus.

The out-of-focus women behind the ball carrier are a mere few feet away - but the depth of field was plenty shallow.
Also, shoot at the highest zoom level possible or appropriate so that you can capture expressions and personality in the shot. Of course, the higher your zoom level, the more difficult it is to keep your camera stable enough for a sharp shot. The standard rule of thumb for zoom shooting is that your shutter speed should be about equal to the inverse of your zoom level. For example, if you're zoomed in all the way using a 300mm lens, your shutter speed should be 1/300th of a second - minimum.
As I mentioned, this is the standard rule of thumb - but it doesn't work for me. Personally, I need to have my shutter speed be a bit less than 2 times that of my zoom level. That is, if I'm shooting at a full 300mm zoom, I need to have my shutter speed in the 1/500th of a second range. Experiment and find out how shaky you are. I've also found that it helps to hold my breath when at full zoom.
Some shooters swear that manual focus serves them better than auto focus - but not many of them are shooting sports. Sports - especially fast-paced ones - are hellish to shoot with manual focus. Maybe after years of practice one could master the technique, but I've found that my D70's autofocus capabilities suit me just fine.
