This is weird. How can it be so difficult to reset Gnome back to default theme, icons, and menu items?
Its not difficult, its just that you have non CentOS components installed there. Do you have an external non-CentOS repo enabled ? like kde-redhat ? Some of them will make major changes to the whole gnome look+feel to suit their own requrements.
Also, check what external components you have installed with something like this :
rpm --qf "%{NAME}.%{ARCH} : %{VENDOR}\n" -qa | grep -v "CentOS"
See anything interesting ?
