Kalaloha, the sawing we did was for things like sawing holes for plumbing & outlet box cutting, things that are not possible to do with "score & snap" (& we did use either respirator or vac recovery when we did any sawing (be aware that even the score & snap can bring up dust...). We did not use RedGuard in our wet ares, instead went with the Schulter Kerdi membrane system for our no-barrier 6ft shower/wet restroom, mainly to not have to redo the whole floor & used the Kerdi integral drain system....
Decoupling can be done with many products, with each having pros/cons list (be aware that metal roof systems attached to metal framing will also be area that may need decoupling, as the heat conduction can also occur there. Our framing system has extruded integral aluminum that penetrate the wall envelope, so we added a insulating reflective barrier within the wall to minimize heat exchange, as decoupling was not an option.
