So we are saying that 2 is a fold and 3 is a call because in 3 he shoves, as opposed to leaving most of his stack behind?

Hand 1 I think is interestings... if this is the first time villian 3-bets us, are we better off giving up, assuming that he's got QQ+, or shoving to show that we shouldn't be 3-bet light?

1 seems much better than 3, since you are not really getting a huge overlay for a 55-45 coinflip in 3, and he can fold in 1. And you have no read that he's stealing here. Or is there something telling in the limp-limp-raise-3-bet-4bet a/i. pattern.
