well regardless of what Mike said your rear suspension setup needs a little attention if you want to get any flex out of it. No biggie, just move your rear hangers forward about 3 inches and you'll actually use some of those 12" travel shocks. Your bumps should be limiting your uptravel, I'll assume Mike said your springs are limiting axle travel before the shocks have a chance to bottom out because with 8" to the bumps and 4.5" of shock left, something has to.
Front looks good, you definitely have room for 35s.
do this for giggles, measure how much shaft is showing under full compression and how much is showing under maximum droop. the delta will be your suspension travel, with 12" travel shocks you would probably like that number to be at least 10 or 11.
