Calibrate the plasma? Does that mean adjust the brightness/contrast etc.. ?
Yes, with a calibration DVD. There are 4 different ones on the market. Amazon has/should have used ones.

Not sure what you mean here. But I suppose that component is technically the best? Try calibrating the set and see but you need to calibrate the input video source, component or other.
