mindmelda,
Here are a couple of books that I know you would enjoy:
"Who Wrote the Bible?", Richard Elliott Friedman. He provides the name of the person most likely to have cobbled together the various parts of the first five books. I should comment that the last of those books, Deuteronomy, was more than likely writen by just one person, Jeremiah's scribe, Baruch.
"Liberating the Gospels: Reading the Bible through Jewish Eyes", John Shelby Spong.
As everyone knows, Spong is controversial and confronting in the extreme, and is therefore essential reading, if only to provide a challenge to one's belief system and as a check on what one holds dear. Another most interesting and arresting book of his is, "Jesus for the Non-Religious".
