"Glued and screwed" is the route I took but with a couple extra steps a long time ago converting my garage to an audio room. Used double 1/2" sheetrock along with 3 headers between each stud. Along with concrete slab this room was solid.
Here's a little story from a few years ago.
During a period of sanity I temporarily left audiophileville and the structure was modified to function as a garage again.
One night three years ago a young drunk driver decided my house was a street and plowed right into the outside corner of my garage. The siding, the corner, corner of the garage door, fence, and landscaping were pretty messed up. The interior a couple cracked studs and a little drywall wrinkling. The insurance company could not understand initially why the garage did not partially collapse. Not a common building practice that our kind strive for I guess.
Anyway, pertaining to your vibration concerns Herbie's advised me about Permatex Blue. Stuff is used for gasket sealing and is also great for vibration control. It is the consistency of toothpaste and solidifies in about 30-60 minutes. I have it in many components with excellent results. Maybe it can be a benefit in your project.
