Get at least a 35mm lens, 28 if you prefer, 24 if you have the balls. Shoot bw film.
Reasons? You won't be wasting shots, and for such things you want to think about what you're doing. Anticipate the action, it will save you ass and give you the best shots.
Good advice comes from who cannot give a bad example.. I'd be glad to go there.
