I would recommend searching on amazon and going by reviews which appeal to you.
I refer to Professional Apache by Peter Wainwright from time to time, though I must say apache is extremely simple even in the most complicated environments. Try and see if you can get by with on-line documentation (terrific manual) and support forums.
MySQL by Paul Dubois is absolutely fantastic. Heartly recommended.
Professional PHP Programming is a great book to start off with.
