Anne, Congratulations on the 300s!
Before I got my D300, I read Ken Rockwell's guide and the Nikonians D300 guide many times over, although I shoot in RAW, so there I disagree with Rockwell. His overview of the menus is pretty good if you take his recommendations with a grain of salt. The camera's instruction manual is good, too, if you have one. There are also many good YouTube videos on various parts of the menus.
After I got the camera, my wife got me the Magic Lantern Publishing guide to the D300, which is good, too. I use it as a reference--when I come upon an unfamiliar setting situation, I go there.
Due to the sheer number of options you have with this camera, I found it valuable to read through the menus sections of these guides and familiarize myself with the menus.
I have now had my camera eight months, and I feel like I have a good understanding of the functions I use.
One important setting is ISO. You have the option of setting a locked-in ISO or going variable. If you decide to let the ISO vary, you can set a low and high limit for the camera. I set mine on variable--low limit 200, high limit HI-1, which is 6400. Others here will disagree with me on the high limit, but a little noise in low light doesn't bother me. (I used to love the grain in fast B&W film in the old days, too!)
Many of us here will be happy to answer your questions as they come up!
