1st part: perhaps. In actuality you are not doing exactly that (though it could be close for the first bit back), but you want to turn your hips flat and sharply inside and you want your hands to come inside as well. Doing this hip move will aid you having the inside hand path, and vice versa.
2nd: not totally sure.
Though I would imagine you could hit anything from pulls if you hit down on it a bunch/come out of your tilt in the ds with your low hand too on top of the shaft (path to left) to slices and hooks. (if you tilt in the downswing/work your hands back to the inside, under the shaft)
It is a fine line. You don't want to take it back too inside either. But if you are a slicer it is probably best to err on the inside path.
