I think Mac said something to the effect that the eyes are the portal to the brain and also affect our balance. He's researched the bioscience behind EVERY facet of the swing. He wants the eyes to be as parallel to the plane as possible into the follow-through and finish. He would hold a clubshaft parallel to the plane line on the follow-through and tell you to keep your head and eyes parallel to it.
I don't know the answer to the grip question. I can say, however, that on the backswing once the hands get to hip high (P2 position as Mac calls it -- there are 8 positions to the swing) the right wrist begins to cock so that the clubshaft doesn't get under the plane. I'm sure many will dispute this, as I know from Yoda's teachings that the right wrist should never cock, only bend, although I think Homer merely said it was "ideal". I have struggled with this issue, but if I don't feel like there is some cocking of the right wrist I seem to get the clubhead too far inside and off plane. Perhaps I can get some help with that issue on this forum.
One other point I forgot to mention. At the top of the BS, Mac advocates a straight trail leg (not locked though), much like Sam Snead.
