If you are going to choose from one of the Godfather movies, then I suggest that you go with Godfather II. It has a lot of subplots, twists, etc. that are perfect for what you are looking to do.
As for a book, well you may want to read "The Five Families" by Selwyn Raab. He is pretty accurate in his writings and basically covers the history of the five families in New York and their affects on the mob in general.
