First make sure that in the "/etc/sysconfig/network" file you have "NETWORKING=yes"
At the very top of your chkconfig --list, NetworkManager is turned off. That may or may not be intentional but NetworkManager starts the dhclient process when it is being used so that you can get an ip address through dhcp. If you intentionally turned it off, make sure ifcfg-eth0 says "NM_CONTROLLED=no" so that NetworkManager isn't in control of that interface.
