basically the reverse gears are for the high pinion diffs, they don't actually go into a reverse rotation just cut in the reverse angle so the drive and coast sides are in the right position for the pinion coming in from a different angle, Reverse rotation has just been adopted as the standard way of saying it.
As to which one you need look at the diff and notice where the pinion goes into the case, if it's below the centerline of the axles then standard rotation, if it's higher than teh centerline of the axles then reverse rotation.
Hope thats clear, and helps

Oh BTW that only counts on front axles if your talking about a rear diff, then they are all standard rotation.
