I actually used the Room EQ Wizard (REW) to analyze the room after some initial "standard" trap placements (corner traps, 1st reflection mirror points, etc.). Once I had some readings that showed some "problem" frequencies, I used a mode calculator which generates a theoretical set of frequency modes based on the exact dimensions of my room. I looked at this list, compared it to my actual readings, and this helped me decide where I needed more trapping (front/back, left/right, or floor/ceiling).

This is still an issue, and will be dealt with in phase II of the build out (sometime next year???). Sound travels up into the rest of the house from the live room for sure since I have really done nothing to work on the soundproofing aspects of that room. My plan for phase II is to tear out the entire ceiling in the live room, and beef it up significantly with lots of mass and insulation (and probably resilient channel). I will also plug up all of the "can" lights and make everything surface-mounting. The can lights act as "sound channels" to bring the sound right up to the floor in the rooms above.
I will also build and install HVAC silencers for all of the live room ducts and returns. This is a big source of sound travels!
Finally, I will seal in the live room with a wall and solid door to keep sound from going up the stairs.
In the mean time however, I am going to have to live with the current scenario, and do my best to utilize the iso room (which is "sound-proofed") for loud amps, and just realize that drum tracking is going to drive my family crazy for a bit longer. They are used to it however as we have been doing this for many years in the old basement room.
