Thanks for the helpful guide! A couple things of note that I noticed along the way:
If you're replacing the screen lens, make sure you line it up properly so the end result isn't crooked.
Make sure to organize your screws, a mismatched screw can poke a hole through the shell.
Be gentle but firm when tightening a screw. I definitely messed up a screw or two being too forceful.
(I might be stupid) keep an eye on the battery lid screw hole. Mine ended up warping so I had to duct tape the lid to the shell.
If you're doing a button replacement too, be careful with the triggers.
