Use vi (or your personal favorite text editor).  If you are working 
on a Redhat system edit the file /etc/sysconfig/network.  It should
be obvious which line to change.

At this point stop and start (or restart) some of the init scripts in
/etc/rc.d/init.d (again if you are on a Redhat system).  Other systems
put things in slightly different places.  If worse comes to worse 'grep'
around in etc to find which files have that information.

Yes

No.  It is was a good question.  One of the strengths of Unix is that
the configuration of the system is done with text files; so no MS type
'Registry' crap to deal with.  If you ever need to modify a system,
all you need is a text editor and little knowledge, no special utilties
required.  Nice thing to know if your X11 configuration ever gets hosed.

Good Luck,

Paul
