This looks all very familiar having just been there. Of course your's is worse than mine, my cover didn't get torn up. It is nice that you can do this repair without having to remove the transmission! Once you torque the nut by putting the transmission into 2 gears at the same time and then hammer it over on the flat it should not move. I would recomend you use a magnetic drain plug so you can catch all the metal that may still be in the case.
