Roger that.
Oil/gas are usually bought from tent. No need to kart it along. (What a pun!).
Technically you are going to use their tools too. I like the list, though and that’s what you should go with. The idea is to try to prepare yourself, so despite tenting, bring your list.
One final thing to add: transponder. This will be necessary to get laptimes on days when they have beacon up. Also needed if you are going to race. Can be bought used (there’s a gentleman who posts with used ines regularly here) or bought from Mylaps.
