Well if you're not bothered by using the TV to switch your video source, and then going to the receiver to switch the audio, just run the video right to the TV.
As for image quality, you are right in theory that there would be a loss of quality by running things through the receiver, but I really don't think there is any perceptible difference, assuming the receiver can handle high definition signals properly.
I would just run things right to the TV if I were you.
