Set the camera on continuous shooting mode. When you are panning or shooting some action, this will give you the best chance of capturing 'the moment'. Remember, if you are going to shoot some static stuff, spectators, bigwigs etc, you might want to go back to single shot mode. Also with the non-action shots you might need a bit more DoF than the action stuff, so apature priority (or program/auto) would be a better bet for this.

A monopod might be useful if you have one, not so much for the action, but the set pieces/spectators, or just long-range shots in general.

Don't forget, a bit of blur can add to an action shot, particularly close-up action, so experiment a bit with slower shutter speeds.

Finally, take plenty of memory, and above all, have fun.

Others will be able to make more suggestions. Looking forward to to seeing the results.
