Issues Upgrading to 13.04 from 12.10 from 12.04

After upgrading, booting into Unity (Ubuntu Default at the login screen) I see just the background image and nothing else, no status bar, and the Windows/Command/Super key does not work as expected. YouTube and other videos play, but no sound. I can only get the Gnome (and it looks to be Gnome 2-ish, definitely not the Gnome 3 I'm used to) shell to work completely.

david@poseidon:~$ lspci -v | grep -i vga
01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880 [Radeon HD 4200] (prog-if 00 [VGA controller])

Any an all help appreciated, and if I've not provided enough detail please let me know.
