Replacing the uppercase is a bit of work as you are stripping down the system and rebuilding it. I recommend you don’t attempt it. Its clearly a more advanced task. As far as the TouchID you need to be very careful as the ribbon cable is very delicate! If you damage it thats the end! Once you get the logic board out you’ll be able to see the screws which hold it in. The cable has a tricky route and is glued in a few places.
