also.. are people using the 'close' nipple where it is really short and fully threded.. or are like a 3" nipple where the middle has no thread

Use the shortest nipple you can find. You may have to use a spacer of some kind to take up some slack if unable to tighten the nut all the way in.

A 2" hole should work but I'm not so sure about drilling a hole that large through a thin curved surface. The bit may start wandering and you may end up with a not so clean, bigger hole which you don't want.
