I did almost the same thing and I'm in the same state. In my case, I was
trying to give my Ethernet a static IP. Now, for whatever reason,
NetworkManager (maybe better called NetborkManager) has all the
interface config grayed out and it says "System eth1". If I try to set
DNS configuration in system-config-network, it gets overwritten whenever
NetworkManager does its thing.

Any assistance in diagnosing what's happening would be of great help.

As a base question, are these two utilities supposed to play well
together? If not, why aren't isn't there correct conflict information in
the RPMs?
