AAAAAHHHHH!!!  Please consider undoing that change right now:
        chown -R root /root
otherwise any process owned by guest can change root's private files. 
(Okay, there's probably nothing critical in there, but if you're like me, 
there's information in there you don't want anybody getting at.)

As for your shutdown problem, maybe an suid wrapper script will do the 
trick:
        #!/bin/sh
        exec /sbin/shutdown -g o

Save as /usr/local/bin/user-shutdown.

Then create a group called shutdown in your /etc/group file (or use 
groupadd).  Add the guest user to this group.

Set permissions on /usr/local/bin/user-shutdown so that only members of 
the shutdown group can execute it:
        chmod 750 /usr/local/bin/user-shutdown
and make it suid:
        chmod u+s /usr/local/bin/user-shutdown
