No problems with hanging cabinets on the wall. my earlier point was just that you don't want to do any noisy work on the lower cabinet countertops if they're fastened to the wall.
I do like the staggered studs idea as it will reduce vibrations through the wall. but remember that the wall will still be nailed to the top plate, so if you have living quarters above, you will still get some noise up there. So that's why decoupling the drywall from the studs and joists is important.
