Keep the people to a minimum. Crowded pit can make for a disaster waiting to happen. And no music. Can be quite distracting at times.

Clean cord arrangments. Chargers out of the way but in easy reach. Make sure chargers are set right before leaving for the night. (Coming back to faults on your chargers, not a good 8am wake up call.)

The usual safety and first aid kits. And for those in the VCU regional, proper hand sanitation. Norovirus is making the rounds. Let's not have another 2004 please?

Folding and camping chairs are good to keep on hand. Don't plan on sitting in them long or often but never hurts.

Laptops should be in a stable place whenever possible. (Watching a team's programming laptop take a dive hurts)

Food and drinks. Depends on your regional but at least keep some water around so key people don't have to leave.

Not safety or killer stuff but:
NEVER leave your pit empty. Judges come around, you've got a wasted opportunity. Some with alliance partners.
When teams come around for information, Don't be afraid to see if they can come back or hand them a pamphlet. Frees people up.

Otherwise, just use common sense. And if you're a rookie team, look to your fellow vets to help you out. Coopertition.
