I am interested in knowing which binary runs the who and/or w command
I want to limit this to specific users on the system - so not just anyone can run it

Welcome to the forums!
Check the coreutils package for the w and who commands.oz

To find the binary you can do the following:
~$ which who
/usr/bin/who
~$ ls -l /usr/bin/who
-rwxr-xr-x 1 root root 33180 Apr 4 2008 /usr/bin/who
To restrict usage to a specific group you can issue:
~# chown root:<group_name> /usr/bin/who
# replace <group_name> with the group you want to allow running the command.
~# chmod 770 /usr/bin/who
You can do the same for the w command.
You will probably have to repeat this whenever the coreutils package is updated.
