The Nikon’s Hands-on Guide to Creative Lighting DVD was a hit (unfortunately in the US only). Here is some very educational behind the scene footage:

Now, we also have a printed guide (by a different author) which hopefully will be available world wide:
The Nikon Creative Lighting System: Using the SB-600, SB-800, SB-900, and R1C1 Flashes
The same author (Mike Hagen) will soon also release the Nikon Capture NX 2 After the Shoot
