When you log-in in single user mode, you are root. Have you looked into using 
nicl (the interface to NetInfo Manager from the command line?)

When I had a similar problem, I booted into single user mode, did mount -uw / 
and then was able to fix things. (Actually, my problem was that I accidentally 
removed all of the admin users from my Mac). 

Try this:
Once you have mounted the hard-drive, type 'visudo'
This is how you grant users permissions to do stuff as Administrators (in a 
unix world). For a user that you have access t (i.e. you know their password), 
add a line to grant them permissions like this:

username        ALL = ALL

Then press 'Escape' and type :wq to exit (you were just in the Unix text 
editor, vi).

Now when you boot and login, the username that you just modified will have some 
admin privileges. You may be able to use the System Preferences interface to do 
the stuff that you wanted (I can't remember if you can), but you will certainly 
be able to use nicl from Terminal to update the NetInfo database and grant the 
privileges that you need.

Hope that this helps,
