don't know about books, but the scott hinds youtube videos, and the DVD by Mark Rubin and Kevin Smith "Ungentle Art" are both great videos to help you get your rockabilly on.
The Lee Rocker dvd is fairly useless, the Pete Turland one I learned a lot from.
The Ray Brown Bass Method book is good, mostly scale and interval exercises. The best thing about it is that some of it has fingerings. Those are helping me a lot with my left hand. Haven't worked through more than the first few pages of it but I'm glad I bought it. Probably would be best as a text to go with some lessons.
I have Lee Rocker's video and would gladly give it away, it really is just for promoting his new band, I have watched all the memphisevil videos they are great I just wish he would slow down a little so you can see what he is actually doing. I have bought a couple basic books about scales and modes, sight reading and music theory. All of them have helped.
