As many of you have done drywall in your lives, there's nothing too exciting to report here. The old stuff was 1/4" with a paper "paneling look" face. The old insulation wasn't faced, but there's a paper barrier between the aluminum siding and the 2x3 frame. For that reason, we're installing the new siding with the faced side facing the outside. It also mentioned installing it that way on the Owens Corning insulation instructions, for "Florida and some gulf coast states". (We're in FL)
The only issue was the 2x3 that runs underneath the window (I know there's a term for it but I dunno what it is) .. it sticks out 2 or 3 mm past the 2x3 studs that run perpendicular to it. So we're just not going to put drywall over that particular 2x3, and instead work up some type of window sill / window trim deal to cover it.

The hardest part was removing the 50,000 staples that held the old drywall up

In case you decide to do this and your old drywall is held up with staples, I was able to quickly remove staples with a pair of 14" channel lock pliers. Just grab the staple and pry it out like you would a nail with a claw hammer.
