This is probably mentioned in the thread: (Not sure what your schedule is like, but)
- Frequent the track as often as possible. Even if you aren't training or racing. You'll learn a lot by watching others train and race.
- Volunteer: Most tracks can't function without volunteers. You'll learn a lot and ingratiate yourself with others. Even if all you are doing is raking leaves on a work day or ringing the bell on a race night. Keep an eye out for calls for volunteers however the track staff communicates (email lists, twitter, FB, etc...).
- Ride as much as possible (during training periods), even if you aren't doing structured training. You can do the most basic things like 30 laps at a time or intervals (1 lap at speed, 2 laps cool down, repeat). This helps you learn the curves of the track and you become comfortable at speed.
- Every track has its own culture. What we say here might be slightly (or very) different at your track. That's why it helps to go a lot and meet people.
Oh, and a random thing that I've only seen from the crit guys/ladies: Take stuff out of your jersey pockets. I've seen keys, wallets, water bottles, cell phones, etc in jersey pockets...all hop out and on to the track..
Your bag is only a few feet away in the infield. Just stow it all there
