Welcome to Nikonians, it's a good group and there is a lot of feedback and information to be had.
I started in film too with a Canon AE1 and then a Nikon N75. I wasn't a pro at the time and shot mostly Kodak VC160. I also come from a graphic design background and one other place to start exploring is the White Balance settings. These can make a pretty big difference in the shots, and the settings lend themselves to some really rapid color abstractions too if you enjoy experimenting. However, I do a lot of my refinement in post, not in-camera. There are too many articles online/books to mention but one I like in general is Photoshop for Photographers by Martin Evening. It has its up sides and down sides but in general I have gotten quite a bit out it for post.
I too am new to the D700 and so far I really like it. I hope you enjoy yours.
