Your graphics driver version is dated November 30, 2011, so if Catalyst 13.4 is installed the driver certainly isn't current (unless that's the latest driver available for your card, I'm not sure - notebook graphics drivers are idiotic).
The audio driver did not install, try installing it again. Realtek likes to uninstall the previous audio driver before installing the new one for some reason, maybe the installer didn't launch again after restarting Windows.
Atheros just released a new Ethernet driver; please try install it.
The MEI driver is not necessary, you can ignore it.
