The Kristin Boese book has a chapter for beginners, then safety, gear, and another one about wave kiting.
But most of the time it explains tricks (very well presented), and it gets up to blind judge, kiteloop double backroll, f-16, kiteloop to blind, unhooked downloop s-bend..
So at least I have not outgrown this book yet.

About the Real dvds: The first two are fantastic for beginners! Joyride is produced very well also, but is not particularly advanced - boosting with grabs, back- and frontrolls, that's it. Probably the triple s covers more advanced tricks?
