Am I just over-thinking it and will it be OK to have the rear end higher than the front of the car?
Another trick is to use a bit of the new fluid to flush out the old. After you drain and before you put the drain plug back in, pump a bit of new fluid in the fill hole and it will help flush out some of the remaining old fluid. And since you don't need the full 2 bottles to do the change, you have that extra bit already in hand to flush with.
