Generally you will use HDMI for video and optical or digital coax for sound whenever available for the component. Some use component instead of HDMI. Your choice, both are good. Don't run your sound through the tv and out the optical out of the tv, you will lose surround sound. Run the sound directly from the component into the receiver.
If your receiver has HDMI in and out and supports video and sound thru it's HDMI, then just HDMI for all you can set up that way.
Sony VCR will probably be S video or something like that with stereo cables.
Depending on what each component can output, the level of quality for video is: 1. HDMI, 2. Component, 3. S-video, 4. Yellow Composite
For Audio the level is: 1. HDMI, 2. Optical cable or digital coax cable, about equal, 3. red and white RCA plugs.
So just check each component and chose it's highest level of output and use it. And for best sound, running any sound cable directly into the receiver rather than thru the tv will give better sound.
