I just finished processing my shots of this, as a matter of fact...
First - it should be obvious, but definitely keep your flash off! Otherwise, you will likely get a visit from a cast member. (It happened to someone in the same aisle as us.)
It's certainly not the most challenging thing to shoot on property, but it will be tough with a PnS. I pretty much left my camera in "P" (biased for high speed) mode. It didn't hurt that we got a seat right in the front, about six rows back, right next to the runway. I think I did pretty well in terms of reach with a lens that maxes out at 135mm - if you're farther away, extra zoom may really help, but I wouldn't want to go slower than F2.8. Shooting in raw is good; if your camera can't shoot in raw, you may want to try turning down setting the color curve to "natural" instead of "bright" or "vibrant" or "chrome" or whatever your camera calls it - the colors are pretty vibrant already and shouldn't really need extra boosting, they may end up looking really unnatural.
Here's a few shots along with the exif information:
Here's one where they were right by us: ISO 400, 135mm, F2.8, 1/120th:
Another close-up... ISO 2200, 135mm, F2.8, 1/120th:
This one had more white balance adjustment than any other - would you believe, 50,000 and +80 in Lightroom? Obviously it's not quite the "true" color you see during the show but it's more natural. ISO 800, 95mm, F2.8, 1/90th
A fairly bright scene here. ISO 280, 108mm, F2.8, 1/120th:
ISO 560, 90mm, F2.8, 1/90th:
ISO 800, 135mm, F2.8, 1/120th:
Also - if you've never seen it before, I'd recommend just sitting back and enjoying the show - worry about taking photos on the second viewing.
