Hands in, hands under.... not really fond of either of those. Really your hands will go "in" more yes, but they're just going on the plane. Virtually everyone takes them "out" and "up" or "above," so feeling the opposite is one thing. Actually DOING the opposite to an extreme would be bad.
Tough to say, frankly. If your hands are deeper than they've ever been odds are that they're going to be more in the entire way down as well. They might still kick out over the top a bit but they'll be more in than when they were out and then over. Better to be "in and over" than "out and over" if you know what I mean.
The release you'll get to later...
Tough to say without seeing your stance...
Whatever works for you. Hands forward a little bit is the "stock" position but we've had people who have them farther forward and farther back. Depends on how you get back to impact more than your setup (though setup can contribute to some various loading rates).
