Hey here's another question, for my interior walls, does it make sense to do a staggered stud wall WITH whisper clips and double drywall, or are staggered studs pointless after already decoupling the drywall? The mechanical room is going to be right next to the theater, and the furnace gets loud.

Great question, and you've got it figured out. The wall can be decoupled by any of the following means, rated lowest to highest performance:

Resilient Channel (RC-1)
Staggered Studs
Single stud with Clip&Channel
Double Stud

Pick one, but not more than one.

Awesome, that makes sense. What do people normally do for mechanical rooms, drywall and insulation on the ceiling in there will be problematic due to wiring and pipes, but then I'd have a gap in drywall from the top plate of the wall to the floor above.

Should it be something like this?

Well, one of the things we want to do when soundproofing is to limit the amount of vibration that enters the original structure. Once the vibration enters the old framing, it is conducted who-knows-where. That subfloor and all those joists would get hit with sound and conduct to some degree.

The upside is that the room next door would benefit from the treatment you proposed.

Yeah the room next door (theater room) is what I'm most concerned about. On the floor above the sound of the airflow through the ducts is louder than the sound of the furnace itself coming through the floor anyway, plus I won't be watching movies up there.

Back to the XPS intallation, what am I supposed to do around windows? It's easy enough to cut around the window and seal the seams with spray foam, but how do I frame the window in with wood and drywall while avoiding moisture issues?

You will need a ceiling in that furnace room, possibly fire rated, check with your local AHJ. Ask about the fire-stopping, too; How to fireblock framing

Why do I need a ceiling in there if I'm not finishing the room? Here's the guidelines pdf for the city of Ankeny. I called the main inspector and he didn't mention it. All the wiring and plumbing to/from the main level of the house goes through there, so if I can avoid covering that stuff up with drywall it would be great.

Usually, if finishing a certain percentage of the whole basement (50% around here), you are required to bring it all up to minimum safety Code for fire prevention. Drywall on the walls and ceiling are required in most spaces, etc.; "CEILING HEIGHT. The clear vertical distance from the finished floor to the finished ceiling." From your basement guide - "TYPICAL CONSTRUCTION
 Drywall - walls: 3/8" limited to 16" oc studs, 1/2" or 5/8” limited to 24" oc studs;
ceilings: 3/8” limited to 16” oc perpendicular to joists, 1/2" or 5/8” @ 16" oc either direction, 1/2" or 5/8” @ 24" oc perpendicular to joists"Underline and color change is mine.
The whole purpose of drywall is to slow the flame-spread and smoke emitted from wood frame joists, studs, etc. from burning through quickly before the house collapses and give firemen time to extinguish it and occupants time to leave safely. Not covering exposed wood frame materials in a mechanical room with electric, gas, other- units there would be counter-productive and always check locally. Let us know the outcome....
