Ron's rules for GC photography:
1. Get a big-arse memory card...8 gigs or larger. Shoot everything!
2. Shoot into the sun, with the sun behind, with the sun to the left, sun to the right (feel free to replace the word 'sun' with the words cloud, moon, lightning, rain and snow.
3. Tilt the camera, stand on your head, shoot close up, shoot from a distance.
4. Get two lenses...one a long distance lens and another for wide-angle, panoramic shots (I don't have the latter...might be purchasing it soon!)
5. Use automatic or manual setting, whichever you feel more comfortable with.
I have shot many courses while playing and it is a bitch for me and the playing partners. If you REALLY want to shoot a course properly, you can do it in 2 hours with a cart. If you're looking for THAT shot on a small number of holes, plan out your strategy.
