You probably forgot to list it, but you'll need a decent tire gauge to ensure your tire pressures are kept in a suitable range.

Yes, drivers put the things they take out of their car on the paddock surface. It's good to bring a plastic bin or two for the things that will fit, along with a tarp to cover everything in the event of rain.

Some drivers bring ez-ups and camp chairs. They're nice to have - make sure you have a way to keep the ez-up from blowing away if a wind comes up.

Bring rain gear to wear in case you end up having to stand around in the rain. Note that you won't wear that gear when you go out on the track - it's just to keep you dry in the paddock.

Bring PLENTY of water, along with some quality snacks to ensure your energy level remains high. You'll be told multiple times that if you're not peeing clear urine you're not drinking enough water. That is good advice. I buy a 24-pack on the way to each event, and it's generally all gone by the time I get back home.
