Specifically, I don't remember whether or not you need to fiddle with that ring in order to make sure everything (gas tube, etc.) lines up during installation. If the guide you're using doesn't mention anything like that, then yeah, definitely no point spending money on unnecessary tools. Anyway, you can always run out to Home Depot and buy a pair later if they do turn out to be needed.
