cub1 - I would recommend looking thru the recruiting thread. There are many old threads on the subject a fit. Each person's fit depends so much on too many individual factors to compare to each other IMO. I think everyone should look at the college website, check out current and old rosters - gives you an idea of how many kids left and are coming in. Remember to look at the juniors on the rosters as they are possible JUCO transfers which might indicate a big loss and they need experience or it might indicate a common practice. You can check the prior year's stats to see who played (i.e. does this particular program play freshman/sophs). Location, money offered, size of school, level of play are a few of the common things that most people discuss.
As far as questions, a 16 year old is too young to receive phone calls from coaches, so if you're visiting schools a coach will probably discuss where that player is in HS - is he varsity, position, grades, etc.
Also, don't forget to the see the recruiting timeline in the front of the site - many wonderful tips and articles there on recruiting.
