You pretty much listed off everything you need and hit the nail on the head...
Just make sure to double check your battery's that they are full and properly charged and test your guns to make sure they are all in 100% working condition so you don't get surprised 5 minutes into a game.
bring some allen keys just in case you need to adjust your motor height or w.e in game along with some smaller tools too.... (screwdrivers, knife, needle nose pliers...)
and I find that a roll of tape is always needed by at least 1 person on game day....
