When you're trying to attain the fastest possible shutter speed, you're doing a guess-and-check method by using Shutter Priority, as you have to manipulate both shutter speed and ISO in order to try to stay at the fastest speed. At that, you'll always be changing shutter speed because of varying light conditions. If you know what the average ambient light is for the venue and you have a stop or two of dynamic range, you can set your camera on manual and just shoot away.
If you use aperture priority, and leave the camera set on the widest aperture, the only variable you need to manipulate is the ISO speed after that. You only then need to keep an eye on your shutter speed, as it will be as fast as possible for the given ISO speed you're at.
Generally, 1/250sec stops motion for basketball. For soccer, I have a hard time stopping the blur of the ball for anything under 1/1000sec.
A flash is generally not the way to go on a P&S if you're going to be shooting spots indoors. The range will not nearly far enough and you will not be able to attain a fast enough shutter speed with ambient light on either of the priority modes (because you should never use a flash at long distances in P mode, it will give you 1/60sec shutter speed and the flash won't work as the primary light source).
It's not exactly easy to shoot indoor sports, even with a dSLR and a fast lens. You're basically at the mercy of the ambient light unless you have remote strobes.
