I would put the 4" panels in each of the wall-wall corners. Then treat the early reflection points, which are basically the half way point (between your ears and the monitors) above you and to either side. It's not quite half way on the sides, there is a formula for it. Then spread what's left over throughout the room. If you're tracking in there as well, think about putting another cloud on the ceiling above where a drum kit would be.
