Well - the auto headlights issue is pretty common (had that issue myself, and if you search, there are others who had the same thing - seems that the sensor has a high infant mortality rate) - it's generally just the sensor on the dash by the passenger side speaker - they replace it and you are good to go.

Not sure what P050A involves - it's "Cold Start Idle Air Control System Performance" the description in the service manual is "When cold, the abnormality in the control of target engine speed increase is detected" - they check all sorts of things (leaks, damaged harnesses, various sensor outputs, etc.) - essentially, the idle speed is something other than what it's supposed to be, and there are a bunch of potential culprits.
