Subfloors
Is it any better to put down two layers of 3/4" plywood or is it better to put down one sheet of 1 1/2". I have to have it that thick to match the floor height of the other room?

I had to do that to my living rm [1/2 of the rm was an addition built prior to my purchase] To save a few bucks, I stripped the floor with 3/4" and then covered it with 1/2" [which brought it level] and then installed 3/8" over both new and old. That's been 15+ yrs ago and no problems yet 
I've seen 1" plywood but it was very expensive, never seen any ply thicker than that.

..So, I gather, the 1-1/2"s (or 2 - 3/4" ply) will meet the height of the other room's floor.
Are you planning on putting in a transition cap to bridge the 2 rooms.? -or run flooring thru the 2 rooms?

Then that should be something to consider right there.
You have a chance to select a subfloor height that will result in a flush finished floor. I'd say wait till you decide on what you'll put down.
The 3/4 plywood will already take care of the structural integrity. So you can put that down even before you decide.
