throwing help

[grizzbass]

my 15 year old son is going out for track (mainly so he can learn how to throw so when he's old enough he can do the scottish games). Some of you know him from festivals. 6'1" 181 pounds, squats 310, dead lifts 390, benches 200, so he's plenty strong but knows nothing about putting. I don't know anything about shot putting either (played baseball) and want to be able to help him and make sure he learns proper form. As in power lifting I assume form is of paramount importance both for distance and safety. Is that true? Are there any books or videos the throwers here would advise to help me learn about stone throwing? Are they basically the same in form? Anyway thanks for any advise.
