Are there specific radios t hat need to be flashed as well?
Do you flash Liquidsmooth and Harsh at the sametime in CWM before rebooting?
I think that depends where you live; radios have not been as big a deal with the N4. I suppose you could always get GetRIL from the Play store.
You can flash the ROM, then GApps, then your kernel of choice, all in a row in the same recovery session.
Harsh makes a good kernel. I personally prefer Trinity, motley, and matr1x
