With blinds that high the cards will dictate the outcome. Q3 is a below average hand, I would have tried to limp in with that if he's passive else fold and wait for something like q7+,K7+,JT,Ax or a PP to pull the trigger with. Your preflop raise in that first hand was 1/3 of your stack, better off pushing in my opinion unless you plan on doing a stop and go (hopefully with a better hand than that). You have to be super aggressive with those stacks and blinds and pick a hand to ride with. Read HOH2, it has a section on HU play.
