Snark, the rubber feet falling off is a common issue. If there's an Apple store nearby, stop in and grab some new ones from them. They're pretty cheap...a couple bucks max (might even get lucky and get them for free). If possible, you might want to grab a few extra just incase. Also, any place that's authorized to do repairs on Apples should have them, since they usually have to remove the feet to get to screws underneath them.
