You need to check what classes the track offers.
That sensorless motor you mentioned, while not really that fast, is technically only legal for open Mod, although the track might let you run it until you get a legal setup. Best to buy something you can race legally in a class more suited to beginners. eg. USVTA uses 25.5 novak motors only, ROAR VTA/Outlaw VTA/CVTA use 21.5 motors. Find out which classes they race, before buying any electronics.
Gearing for any of the spec classes, you'll need to change that stock 48pitch spur to a small 64pitch spur in order to get in the right range. 96tooth 64p spur should probably work for most classes where you'll want an FDR between mid 3s to mid 4s.
