Regarding moving Ctrl, my experience is that the pinky finger just isn't strong enough to handle the Ctrl key in emacs even when Ctrl is bound to caps lock. I think it's more comfortable to swap Ctrl with Alt (or whatever key is adjacent to the spacebar) so the thumbs can be used for Ctrl. This is beneficial even in other software, since Ctrl+C, Ctrl+V, and Ctrl+X are pretty common.
