I am contemplating trying to intensify the negative with KRST. However,
there seem to be two schools of thought about this. One says that
selenium
only affects the highlights and thus would buy me nothing here. The
other
says that you get intensification of shadows as well.
Who's right and will this help fix my problem?

I use KRST to boost highlights and contrast. Works well for that.

A few years ago I was in a John Sexton workshop - he uses KRST 1+1
for intensification. It will affect both highlights and shadows, though
since there is not much silver in the shadows (thin areas of the negative)
it won't do a -lot-. You get approximately one grade harder, and the
nice thing is it does not increase the grain (as it would if you develop
for more grade of contrast).
I have used it successfully for both the whole image, and also for
local intensification of a portion of a negative.
I hope it goes without saying that you should have a backup
negative (especially for locally applied KRST) if the image
is important to you.
Joel.
