Unrelated to anything but: Your terminal colours seem a bit brighter than the standard ones in Snow Leopard. Are Terminal's colour capabilities improved in Lion, or are you using that SIMBL plug-in, or...?
That is indeed Lion running there. See the full screen icon on the top-right and smaller buttons on the top-left. I haven't played with it yet but there is much more control over colors in Terminal.app in 10.7.
