This does not look right. Try DEVICE='eth0'

Can't help you too much here. I avoid GUI configuration tools like 
the plague ( Bad juju ).

If not due to the above "DEVICE" setting then I don't know why your 
attempt failed.  Here is a sequence of my FC3 box that I just 
stepped through for the first time on this box and, as you can see, 
it worked as expected:
