11 (resiliant channel) and 12 are quite important, those two alone knock off around 10dba,
Every 10dba you knock off, its about 50% quieter.
I would disagree about the concrete. 1.5" of concrete is a mass load...... 1.5" of concrete is probably worth 5" of drywall
I would look up the STC of every material, and judge for yourself
