In regards to drywall removal, I removed all the 1969 vertical drywall on one level of my side-split home a couple of years ago in order to swap out the paper bag crappy insulation with Roxul as part of a major reno of that entire floor (LR/DR/Kitchen/Foyer) using the Makita Drywall saw that was fairly new to the market at the time.

Hooked up to one of my auto-clean dust extractors (no bag), cutting in between each stud from top to bottom and horizontally doing three cut lines along the top/bottom/middle of the wall, the drywall is easily ripped off the wall in small manageable pieces for the dumster with almost virtually no dust or piles of broken drywall all over the place. Just gotta remove the nails that are left behind some of which will still have a chunk of drywall on them that you need to break off.
Avoid hitting any nails or screws, but one blade had done about 75 linear feet of drywall that time in the manner described and had still been in use since on other smaller reno related jobs til recently. I bought a ten pack of the blades when I bought it and only opened it a few months ago when the blade I'd been using since I bought it was finally showing it was pretty well cutting a lot slower than it should.
This is also the go-to tool now for anything where you used to use a handheld drywall straight saw.
There are also blades for wood specifically, but the few times I needed it for wood, the drywall one worked fine anyways.
In another area of drywall dust containment, this Bosch accessory makes pot light hole saw drilling virtually dustless and a one man job in using it as well.

I've also used their smaller version for when drilling holes for electrical thru ceiling joists.

Note, I do see that another brand is making a cheaper version than the Bosch smaller type now.

I recently pre-ordered the Dewalt Grabo kit in early Nov, but they are on back order here in Canada. Should arrive soon though.
