I have asked these same questions many time and conducted an exhaustive amount of research and I believe my system to be correct as it is currently plumbed. In researching I did find some sites that showed the plumbing different, but the configuration I used is the one most generally used.

Here is a picture of my MC plumbing. The front residual valve is behind the MC, so it is not visible in this picture. MC Plumbing
