The first book is Fair Tax The Truth. I think the second one is Fair Tax, Answers the Critics. Both are pretty good, although I think the first one is best.
You can also get alot of info from the FairTax.org website, or start visiting a community action group and talk to some of the folks who have been involved for a while.
If you have a specific question, feel free to post it. I expect answers will be provided by some of the folks on here.
