Hi Laurence,
I have no hands-on experience with this system, but I do have much
experience reading tech manuals. ;)

The radial setting on the face of the KNS80 is for placing the RNAV
waypoint. The radial setting on the HSI is for choosing a course
to/from said RNAV waypoint. Assuming we are using the same pilot's
guide, look at the navigation example on page 10. We use four radials
on three VORTACs and never adjust the radial set on the HSI.

You are correct, DSP should also flash if it doesn't match USE.

Almost, but not quite. Setting the distance to 0 causes the KNS80 to
behave like same as VOR/PAR. Read page 6 "Linear or angular crosstrack
deviation?"
In VOR/PAR function you have, in
effect, a waypoint located over the VOR/
DME station and thus will be provided linear
crosstrack deviation as in RNAV
