The main things have been covered.
(loose screws, nuts, tyre wear, camber settings, toe settings, belt and diff tension).
I like to have a nut wrench, 3 hex drivers, a metal parts tray, small brushes (1 for cleaning, one for applying additive) and additive on my pit table. That pretty much covers any adjustments I need to make inbetween heats.
The rest is in my pit box, awaiting deployment
If you race on a high bite track with foams, like I do, I apply additive 20 or 30 minutes before the first race and then the grip just keeps coming up so no need to apply any more as time passes... Simples
I'll usually have a single alcoholic refreshment and some snacks close to hand too, for me at my local club it's a good way to chill out and chat with other guys in the pits between heats
