Paul,
It is wise to bond the KXPA100 to the station ground to combat noise and
RFI. In fact bonding everything in the station together with heavy wire
or braid can cure many "strange happenings".
Other than that, you are correct that there is no need from a signalling
connection standpoint to bond the KX3 to the KXPA100. Bonding the
station equipment together and to a station ground point is to keep all
the gear at the same potential and can assist with such things as
extraneous noise pickup, stray RF and other electrical annoyances.
While on the subject of grounding, remember that NEC code requires that
all ground rods and wires be connected back to the utility ground rod
with heavy gauge wire (#6 or larger). This is a safety consideration
and has nothing to do with the proper functioning of your equipment.

PS: Your first post is just fine.

Just wondering how important it is to have connect the GND terminals between
the KX3 and the KXPA100 amp. The KXPA100 manual states the station ground
should be connected to the KXPA100 GND thumbscrew. I was just wondering since
there are many cables connected between the two if the additional GND
connection is truly necessary.
PS: This is my first attempt at communicating on the list and I just wanted to
say how helpful it has been. I have spent many hours searching and getting
information perviously posted.
