Raise to $1.75 preflop, $3-3.50 on flop, as played call the turn.

Pre-flop: Are there any hands that call my $1.25 raise but fold to $1.75? Or are we simply trying to build a bigger pot with AA?

Flop: If he re-raises are we pushing?

Your raise ( to 1.75) is for protection/value.

I don't really understand your second quastion.
Action should howver be like this if raised: Hero bets, Villain raises, Hero shoves.
