Read Mastering the Nikon D300/D300S by Darrell Young. I read it twice! Do so with camera in hand. "Digital Darrell" is just excellent, period. I absolutely love this camera. Don't mess around with after market batteries either. Stick with Nikon EN-EL3e batteries only. Oh, and get a MB-D10 battery grip too. The package is just exquisite! The lenses are up to you and your pocketbook, but I use the VR 18-200 zoom most.
