Where are you at in NOVA, anyway?
Near Tysons Corner

Got it.

1) Check pressure. Let's say you're looking to get 35/33 and you're currently reading 33/31. That means you're down 2 PSI all around, right?

2) Drive to the gas station. Hopefully it's pretty close by.

3) Check the pressure again. It'll probably be reading 35/33 or something like that by now. Make a note of the new pressure and add 2 to it. So in other words, after you arrive at the gas station, you're reading 35/33. Fill your tires to 37/35 instead because remember, you were missing 2 PSI before. If you're not sure, you should add some more air in because it's always better to overinflate a bit. You can always let air back out without a pump!!

4) The next day, after the car is completely cool, check the pressure again. Hopefully it's on target. If it's too high, let out some air to the appropriate target pressure. This is why I said to overinflate a bit to be sure. You can always let out the air now.

Station is about 1.5 miles away, so I'll give this a shot.

With regard to what psi to run, run whatever feels good to you that's at least the factory recommended, and at most the max cold psi stamped on the side of the tire (though that will probably feel absurdly stiff).

Air it up to factory spec and play in 2psi increments to find something you like. Depending on the tire, I've run anywhere from 31-45psi (Continental Extreme Contact DW's have absurdly soft sidewalls)
I have a top notch bicycle pump that actually has a gauge. Somehow I never thought to try this, I just assumped it was not powerful enough to inflate a car tire... D'oh.
