Thanks for all the info. Appreciate it. I will post some of the shots I took on Tuesday night later this evening and see what you think. I think a lot of them are good but sometimes the camera doesn't pick the one focus point I am looking for it to concentrate on and picks another point. I have not done any research on if that is something I can adjust but it could be part of my problem.
You want to set it to single point focus, then it'll always focus at the same spot. If your camera has a "sport" mode (which is likely does), that will at least get you in the ballpark (rink?) of what you want, and you can learn what it's doing and go to the more manual settings from there. The sport mode will set a fast shutter speed and single-point focus. (I'd explain how to do this, but I'm not familiar with your camera, so I can only give general guidance. Someone here will chime in, or the owner's manual will help now that you know what to look for.)
Or you could switch to "S" mode (shutter priority), and set a good fast shutter speed, try, say 1/250 or so to start, and set your ISO up higher to improve the sensor's sensitivity. Set the focus to single point (I recommend dead center because that's the easiest to aim at). Take a few pictures, then look and see if they're blurry/dark/etc. If they're blurry, decrease the shutter speed (1/400, 1/500, etc.) until they're sharp. If they're dark, increase the ISO. If they're sharp and dark, try a slower shutter speed and see if they're still sharp while getting lighter.
Other tips - you may be better off to zoom out if your lens' aperture opens wider, then crop the picture. But that also makes focusing that much harder - it's a smaller spot to hit. It's a trade off.
When reviewing your pictures, don't get into pixel peeping - any picture, when zoomed in far enough, is going to be fuzzy. You're looking for motion blur - streaks in one direction. (Or it could be blurry because you missed the focus, something I do all the time. But that's still different than blur due to motion.)
As was said, indoor, relatively dark, no flash, and fast-moving people is among the hardest thing to do for a camera, and it's where you'll start to notice the limitations of some cameras and lenses (our point-and-shoot model just doesn't handle this type of photography very well compared to the DSLR). I do ice hockey pictures frequently and have similar issues.
I inline speed skate and the rollergirls sometimes come to our practices to learn to be better skaters.
