I would read the book I mentioned above first, its great for setting of the table and will help show that the Jews just copied these stories then changed them to suit their own agenda. Then I would read The Bible Unearthed, by Israel Finkelstein. This book is an archaeology's understanding of what the real Israel and that area was all about and who the people of that area were really. Another one to get is the Egyptian book of the dead by Dr. Ogden Goelet and Dr. Raymondo Faulkner. This book has some of the best illustrations of the scroll and if you study it well you'll see that most of what we are taught in the NT about ones spirit going to heaven, our hearts conditions being judged and they idea of living in a paradise all come from this much older religion.
In response to Brotherblues, its important to bring out to any JW that your talking to that these stories could be said to just be repeated orally down through Noah until finally written down by the Moses etc. Yet there is one major problem all the stories involved multiple gods and not just one and his adversary Satan. In fact this adversary we know as Satan is in fact the very God that saves Noah, is the creator with help of mankind and is the father of Adam. He is also the one who confuses the language, so you may want to ask the JW "Who's god are you really worshipping?"
