I've installed everything using twrp-geehrc. I'm using 20131121 build right now with smoocha kernel and 11-21_GApps_Core_4.4_signed.zip gapps (everything from 1st post).
Of course you install rom first, then kernel and gapps (or gapps then kernel, doesn't matter). To control clocks, voltages, governors, MP-Decision etc I'm using trickster mod.
New qualcomm optimzed bionic and dalvik libraries from MotoX 4.4
