Man you gotta be excited for the dedicated room! If it were me I would think extra drywall, not sure how much. I've also heard of green glue and whisper clips to decouple and further isolate from vibration.

Lukeamdman's Dedicated Theater Construction
Current system configuration:
Subwoofers:
(8) Ported Incriminator Audio Judge 21" (12cu.ft boxes tuned to 14hz)
(2) Othorns (loaded with B&C 21-IPAL drivers)
L/R Mains:
Dual AE TD18H+ in 9.5cu.ft 25hz ported boxes, SEOS-24 w/BMS 4594ND
Center:
AE TD15M in a 4cu.ft 45hz ported box, SEOS-12 w/Denovo DNA-360
Surrounds:
(4) Radian 5210 in .60cu.ft angled boxes. Crossovers designed/built by Matt Grant (mtg90)
Amplifiers:
(3) SpeakerPower SP2-12000 (Othorns and the ported 21s)
Crest CC4000 (quad AE TD18H+)
Lab Gruppen IPD 2400 (SEOS-24 w/BMS 4594ND)
Crown XLS 2500 (center)
Behringer iNuke NU4-6000 (surrounds)
Behringer iNuke 3000DSP (Crowsons)
Processor, EQ, and Blu-ray:
Marantz AV7005
MiniDSP 10x10HD
Oppo BDP-93
HTPC (JRiver)
Misc:
For measurement equipment I have a iSEMcon EMM-7101 and a SoundFirst SF101a. Mic preamp is a Motu UltraLite AVB.
There are 6 circuits dedicated to the amp rack, and a 7th circuit also but that's shared with the room. The SpeakerPower amps are each on dedicated 240v 30A lines, and the Crest CC4000 is on a dedicated 20A 120v line.
Construction:
This area, roughly 12.5'x23' is going to be my dedicated theater space.

On my old system, quad LMS 5400s, here's what the supporting wall would do:
I over doubled the 15-30hz output since then, so I put two layers of 5/8" drywall on that wall which dramatically helped.
UPDATE:
Moved the return air to the other side of the room:

I did luck out in the fact that my front screen wall used to be wood paneling (with studs and concrete wall behind) and when I had my basement re-finished a few years ago they told me I could save a bit if I just had them put the drywall right on top of the wood paneling instead of tearing the paneling down. The wood paneling is very sturdy/rigid stuff so my front wall does soooo much better than my other 3 walls which is nice since my screen is a painted wall. The image vibrates like crazy on some scenes like Flight of the Phoenix but it's not the wall, it's the projector - that's a whole other issue that needs to be addressed eventually.
I'm jealous of you man, you get to start from scratch and make sure it's all done right!

That would definitely keep the supporting wall from vibrating, but that extra wall on the staggered studs would still go crazy.
I think it might be easier to just add another wall on the theater room side and make that the 3-layer wall. Keep about an inch of space between that wall and the supporting wall.
The ceiling is the tricky part since I don't wall to drywall it. All the water and gas lines are there, with a kitchen and laundry room directly above. The odds of water spills leaking down is high, so I want some sort of accessibility to that area.
