Without having followed this thread, wouldn't the whole procedure you 
describe also work with

1. Open a terminal
2. type 'sudo passwd root'
3. Enter the current users password (to allow for the sudo-command)
4. Enter the new root password (twice)

This should work under all versions of MacOSX.

Working with sudo is only safer if you have an appropriate /etc/sudoers 
file restricting rights to specific tasks. Having a users allowed to do 
anything root can do does not make your system any safer.
