I'm not sure gnome-panel is required.
Seems like it'd be better to take the panel lines from the unity2d session and put them in the xmonad.session, and remove gnome-panel altogether.
The stock xmonad.hs will not do, however. This guy seems to have gotten it right: http://www.elonflegenheimer.com/2012/06/22/xmonad-in-ubuntu-12.04-with-unity-2d.html
