Eric Bischoff's book, "Controversy Creates Cash", is a good one. I also like how he doesn't waste a whole lot of time getting to the wrestling portions of his life and career. The most boring parts of these autobiographies is when they go on and on about their family life and their upbringing and childhood and whatnot, which I never really care for and tend to always skip over anyway. But Bischoff takes only a good thirty or so pages before his career in wrestling begins.
Hulk Hogan's book from 2002 (just called "Hollywood Hulk Hogan") is an interesting read too, if you can weed through all the bullshit and lies that Hogan has laced in it throughout.
Never read Chris Jericho's first autobiography, only his second one titled "How To Become World Champion In 1,372 Days." It picks up right where his previous one leaves off, right when Jericho is set to debut in the WWF. I found it to be a very worthwhile read except for the parts about Fozzy and his family life.
Austin's book, "The Stone Cold Truth", and Flair's "To Be The Man" are also recommendable.
