Now the thing is, I just had the battery replaced after the car was sitting dead for about a month (went out of town). Do I need to reflash to the stock ECU programming? Or just drive it for 100 miles to get 'wake the ECU up'?

I would say drive the car at highway speeds to set the o2 sensor monitor and if everything else passed you should be fine with passing. EVAP being incomplete will still get the car to pass.
