I'm nervous as hell, but glad to be racing in my age group. :-) I've only done scratch, keirin, and points on this list. My main question is that I need to gear up. I'm on 48:15 now (restricted gearing for Cat 4s) so I need to gear up but I don't have a lot of time to experiment, so I can't take a lot of risks. I'm thinking 52:15 (90 inches), 48:14 (89 inches) or 50:15 (86.8 inches). Unfortunately, I don't have a 49t with me, but I have 16, 15, 14, and 12t cogs. Again, I don't want to risk it too much, but clearly can't be spinning out on my 48:15. Any suggestions? I am inclined toward the mid option, 48:14, and if I have to spin at 140rpm on some sprint laps, I'm good with that. BTW, for the TT/pursuits, I have a different bike for that and different gearing. I'm already set there, based on my Oregon State Masters 500m and 2k.
A couple of years ago I stole a gear list from the "Learn to ride track" page that the Minnesota cycling federation had up. Here's the condensed version I use:

Scratch: 49/14 (50/14 for 2k or shorter)
Points: 48/14 or 51/15
Tempo: 52/15
Elimination: 49/14 or 52/15
Chariot: 51/15
Keirin: 51/14

Your mileage may vary as this is what I use for under-40s 3s races. The original author suggested going down a tooth when not racing at altitude, so consider that as well. I haven't had the opportunity to test that, so I can neither confirm nor deny.
