So far, low 20s F were the lowest temps I tried starting in, and the engine has been catching pretty fast, with proper pre-glow - no hiccups or any need to throttle with the pedal.

My question is, can I get away with a couple 30-sec pre-glow cycles at 13F before trying to start, or should I plug the electrical cord on the engine into the wall? If the advice is the latter, can someone give me an idea as to how long I need to have the thing plugged in before attempting to start?
Yes, Plug it in! It won't hurt anything. It should be plugged in for about 2 hours. but leaving it plugged in all night won't hurt either. the electrical cost is minimal.
