My take on this:
Use a fast film speed - ISO 800. Remember the faster the speed film the larger the grain. Set your shutter speed on 500th of second and on shutter priority. At 500th of a sec. it should stop a volleyball in mid flight. One thing to consider is that since you are shooting indoors make sure you buy film that is color balanced/corrected for indoor use. If you have mercury vapor lights, well your color is going to be off unless you get a color meter and then put photo gels on the end of your lens. So don't worry about it.
If you find that your meter is telling you that you are consistently 1 stop under exposed tell the folks that are developing the film that you need it pushed one stop. It means essentially that they will develop the film just a bit longer or at ISO 1600 if you are using 800 speed film.
