Congratulations on the new camers. I love mine. Dont forget a copy of the Nikonians Mastering the D700. You can get it on Amazon and in the back there are pages and pages going through each menu option for settings although the standard default setup is pretty good all by itself.
If your camera already has a custom setup take a few shots and see if you like it then refer to the book on how to change them or if you really dont like the resutls theres an option to reset to factory defaults.
Good luck and happy shooting your are going to absolutely love the auto focus on this great camera.
