I will be expanding the upper level of my split-level home. I am going to have a 9 x 11 room to play my drums. In order to keep the noise levels to a minimum, I will install fiberglass bats in the walls. I am considering an additional layer of 1/4" styrofoam over the studs before the drywall goes on. Does anyone have any thoughts on this regarding combustibility, etc?

The use of resilient channel is recommended and not combustible.
Check out US Gypsum Sound Construction for great detail in recommended construction.

Time-Life has a series of books called "The Home Improvement Library," most likely found at your public library. The volume "Special Purpose Rooms" has a section with many good ideas for sound-proofing.
I also suggest that you look into acoustics in general. Covering styrofoam -even the "fire resistant kind- with at least 1/2" of sheetrock is an excellent idea. Covering the exposed face of the wall with fiberglass batts (faced is OK) will also help the acoustics within the room.
The biggest help for acoustics within the room will be to avoid right angles; a rectangular room is simply awful!

If this helps:
We installed 6 MG sets in a room adjacent to office area. The GC came up with this "dimpled" foam stuff. Looked like something you would put eggs in.
Black acoustical foam, about 2" thick, dimpled, & about 3' square.

Either WW Grainger or McMaster Carr has it in catalog I think.

If you're interested, let me know & I'll find item ## & $$$

Rojo-sy (Redsy with Espanol twist-per some older thread),

I keep forgeting that you are a fellow Drummer-Sparky!

Have you considered muffling your Toms? Cymbals don't workout well being muffled, but their higher Hz sounds decay a lot more per distance, than the sound of kick drums, snare drums and toms.

One really good way to get a grip on sound proofing + room tuning is to check out some practice studios.
Rent a studio for a few hours, and either play alone or bring the whole band there for a jam. Also pay attention to others and just what sound passes into the corridors.

For me personally, to reduce the overall sound of the kit (being a 13 piece double kick set with rock style cymbals) I furred out from original walls - only out 2" total. No direct contact between existing walls and the steel studs.
Inserted thin insulation - the stuff used by HVAC installers to wrap their ducts at joints and such - and let it hang kind of loosely in the wall cavity.
Sealed around outlets and at floor/sheetrock joints with silicone sealant (flexible when dry).
Sealed up window mounting points (inside and out), plus replaced windows with double pane setups.
Added a 2x2 T-Bar grid, 6" below the existing hard lid. Inserted R-19 3.5" insulation bats in the ceiling space.

To help "Tune" the room better, one furred out section was "offset" by a small fraction, resulting in a non-equal room size.
This helps reduce the problems involved with crappy sound in a Rectangular Room (mentioned by a member). One wall was offset 2" more at an end.
If you can afford Neoprene, use it to gasket and seal stuff.

Having done some very simple stuff, had a friend play the kit "hard", while I observed from outside.
Sound intensity at 10 feet from the room was equal to normal conversation!
My Wife opened the door, and BOOM!!! Loud As Heck!!!

Good luck and have fun playing!

p.s. what kind of kit do you have?

I currently have a REMO Quadura 5 Pc. with "power toms". Also an assortment of Zildzian & Paiste cymbals. When the renovation is complete, I hope to buy a new Ludwig "Classic Birch" set(jazz size)to christen the room.
