I just came back from a trip to Kitesurf the Earth with Paul Menta. We flew into San Juan and rented a car so we could see more of the island. It is better to fly into Mayaguez though. American has 2 flights a day there on Eagle/Executive air. Try to take the early flight in and out.

Paul has most kiteboarding DVDs and a copy of Kiteboarding’s Simple Plan by John Holzhall.
