Thanks again guys,
The original /mnt/us/kindlevncviewer/kvncviewer.sh file from the original download runs (as per the image below). I get a bit of an overlay of what is running on my PC's screen but only in the black bar at the top of the screen of my Kindle.

However, the corrected 'code' for the Paperwhite located in post 393 in this thread (as below) when saved in Notepad++ as a Unix Shell file (.sh), replaced on my Kindle and run, I get all the errors noted previously (as this was what was being run in the previous posts although saved in Windows Notepad).
Code:
#!/bin/sh
cd $(dirname "$0")
LD_LIBRARY_PATH=.
export LD_LIBRARY_PATH
while :; do eips ''; usleep 80000; done &
lipc-set-prop com.lab126.powerd preventScreenSaver 1
./kindlevncviewer -config config.lua "$@"
lipc-set-prop com.lab126.powerd preventScreenSaver 0

Also, it appears that my /etc/init.d/ folder is empty which would explain why the two commands in that folder don't work. Not sure if these are required to launch the above .sh file via KUAL (which I wasn't doing before... gah.).
