In reply to sip a cup: My vote goes to the following 2:
white circuits book, a big improvement on the old purple version.
Essential fontainebleau, great maps and plenty to keep the casual visitor busy. Captures the essence of the place better than any other guide.
5+6 and 7+8 are also good if you're looking for specific problems though for the first time visitor you'll probably have as much/more fun just wondering around trying anything that takes your fancy.
