I had a new software download installed because of a SERVICE ENGINE warning. Should I have turned my headlights back down prior to this upload?

No, an ECM update does not affect the SUM. And, if you did happen to get a SUM recalibration, if your headlights are pointed where you want them, then you're good to go.
