Copying the settings is a good start.
Since there will be some difference between the component and HDMI because of analog offsets/tolerances on the component interface you might need to adjust it.
The other factor is that the different TV stations are not always consistent in black level or colour settings.
The other thing to look for is that if you get HDNet they broadcast a test pattern on Saturday mornings. Just record that and you can use it to set up the TV.
