The hostname isn't changed by NM because that breaks Xauth and stops you
from being able to launch X apps.  I'd say don't set a custom hostname;
if you're using DHCP then you either (a) won't get the same IP address
each time, or (b) you've set up the DHCP server to provide a "static" IP
anyway.

Add these to your DHCP server's DNS server list.

I think yum can be set up to use HTTP proxies in it's conf file.
