I found one book which was OK on the subject, but it tended to cover more fender/gibson type setups. Have a look for
electric guitar setups, that's the book I have, but it's more about action and
truss rod adjustment and the like. It does have some stuff about flayds, but to be honest, if you look about the forum and the faq area and play about a bit you should be able to find out everything you need to (*with a bit of common sense, logic and reasoning, that's pretty much how I learnt most stuff)
