If you have PS CS3 or CS4 why would you even consider just hitting
mode>grayscale when you could convert to B&W with image>adjustment>B&W
complete with preset that you can load for yourself? As for just using the
red channel? I don't think so. It just does sound right at all. 

 

Just did a screen capture of a red channel only B&W, and a convert to
grayscale screen capture and the numbers don't match. Close but not a match.


There are default setting lurking in PS and I think that you idea about what
is being done there is just that. I'd ask some Adobe folks about it. 

 

As for scanning, you can use the channels for sharpening, noise control, etc
in the scanner software. It is a whole new exposure of a scene. How would
you like to render it? That is the first question and the beauty of it is
there is no ONE answer, but many equally valid choices.

It is true that the direct conversion to greyscale from RGB in 
Photoshop changes to the red channel. You can check this easily by: 
converting an image to greyscale in PS by: Image>mode>grayscale. Go 
to Edit and select 'change profile to rgb'. Go back to Mode>Channel 
mixer and you will see that the red channel is at 100% Don't know 
about scanners.
