Glad you're enjoying the D300! I recently upgraded to a new "used" D200 from a Panasonic SX7 point-and-shoot and it took me a while to get the hang of everything too. And there's still a whole lot of stuff I have left to learn! I found Ken Rockwell's D200 User's Guide to be very helpful, and even though you have a D300 it might be worth reading anyway. Everything won't be exactly the same, but he will probably have some good information that would be useful to you.
