In no particular order:
1) Know your penalty enforcements. There's a lot of subtle (and not-so-subtle) things that are different from FED penalty enforcement.
2) Substitution mechanics... If Team A is substituting, you need to remain over the ball until Team B has the opportunity to match up. Look to the R, he should be giving the "iron cross" signal in this situation... pregame with your R and your wings on how you'll handle this.
3) Initial position on scrimmage plays: 7-8 yards from LOS, behind and to the side of the LBs. Try to stay out of the way as much as possible, but you need to be able to view the ball and the snap at all times. If a runner ends up coming right at you, FREEZE and GET SKINNY. Despite everything your brain will be telling you, moving backward or sideways is the worst thing you can possibly do.
4) You primarily control the pace of the game, not Team A. Try to get the ball spotted quickly (I usually aim to have it down with 32-33 seconds left on the 40-second play clock, unless there's an unusual circumstance).
5) Be the traffic cop. Use your voice (I've had D-I umpires say that if your voice isn't a little sore after a game, you're not talking enough). Congratulate players after they make a good play, warn players that are getting close to the edge ("Hey, #55, keep your hands in").
6) If the play ends in your area, raise one hand over your head (palm up, not a fist). This signals the 40-second play clock to start.
I'll post again when I think of more.
