The books are an okay bed-time read but if you've been using a DSLR already then my opinion is you don't really need them. Just shoot with the camera and use Nikonians when things don't quite turn out or you need a tip or trick for a particular situation.
Editing to say: I bought the Hogan book. A good reference, but there's a lot of filler that I consider of little value and I'm not even an expert photog. I rarely read it.
