Statistically I've had much better luck with my Bradley Method doula clients than my clients that took other methods/"educated themselves". I am a Bradley Instructor and usually end up using a LOT of the stuff that I know from there to assist my moms in labor (which usually quickly relieves DP and Mom).
For books I HIGHLY recommend Henci Goer's "Thinking Woman's Guide to a Better Birth" for every woman...
the second would be based on the person. For VBAC education and empowerment I HIGHLY recommend "Silent Knife"...
I too loved Ina May... but that's definitely more suited for people open to that kind of stuff. Beautiful books though.
