D7000 Guide Book : Suggestion required

Hi,

I have a D5000 and know all features of it, menus etc. (Learned with the book David Busch's Nikon D5000 Guide to Digital SLR Photography.). Now, I bought a D7000. and my question is, should I a buy a new book to learn all D7000 features/capabilities? If there is a guide for D5000 to D7000 upgrade, that will be the best for me. But I cannot find one.

If I buy a D7000 guide, which among the one you will suggest for me?

1) Magic Lantern Guides: Nikon D7000 by Simon Stafford

2) Mastering the Nikon D7000 (Paperback) by Darrell Young

3) Nikon D7000 Multimedia Workshop [With 2 DVDs] (Hardcover) by Lark Books
