Red Hat / Fedora :: Adding Good Repositories For CentOS?

I'm giving CentOS a new look as a desktop. Been a few years since I last installed it on anything but a server. While the default repositories have improved greatly I am still bereft of so much of my cherished and necessary software. No Gambas, Wesnoth (shows up but version is 2 years out of date), Chrome, Audacious ugly plugins, XMMS support for FLAC (shows up but errors out if I try to install), Cinalarra, Audacity, JACK audio, Ardour, Xine, Amarok, Blender, Gthumb, Abiword, gramps, disk utility, many KDE apps, it's almost like KDE is a forgotten desktop manager for CentOS repsositories and pages more of software I'm too lazy too list. All of this is software which shows up in Debian based distros and most of which in Fedora/SUSE repositories.

What are some good repositories for CentOS. I clearly have the wrong ones enabled or CentOS is a very crippled desktop. Here are the repositories I've added/have.
Updates
extras
addons
adobe
base
c5-media errors out so I have it disabled.
centosplus
contrib
kbs-CentOS-extras & misc
Rpmforge
RPMforge extras errors out so I have it disabled.

CentOS users what repositories do you use?
