I'd bet/3bet the flop on hand 1, there's almost nothing he could continue with if he's a tight MT'ing reg. He's the button, his raising range is way wider than your 3betting range, regardless of how light you 3ball.

Hand 2 I don't like the turn check but since you did I think you have to shove over -- too many players float until they can take it away and you don't have enough behind to raise/fold. 25NL players don't typically "pot for value".
