One of my favorite books on church history and the transmission of the Bible is called, "The Indestructible Book". I think it's out of print, but you might be able to get a copy second hand, or I think there was an accompanying video.
Another book worth reading is, "The King James Only Controversy", by James White. While it deals with the KJV-only issue, it goes into a lot of the details about lower criticism and Bible versions.
