Well, I live near Boston. Use of deadly force to protect property is strictly verboten in MA. Also, the bedroom suburb I live in has excellent police response (less than 2 minutes the last time I called for an alarm going off).
I'd grab my pistol, call 911, turn on outside lights, but STAY INSIDE. Yes, you might be able to go outside and get the drop on Mr. Bad Guy. But did you see his buddy who was backing him up for just such an eventuality?
