My workflow adapted to some of the additions in Unity so quickly that it was absurd. At this point I could never go back to something without Super+#, Super+w, Super+s and the other keybindings found here: http://askubuntu.com/questions/28086/unity-keyboard-mouse-sh...
There go my hopes that someone would enshrine a sensible scheme for keyboard shortcuts. On new GNOME installs, I remap shortcut modifiers to
Super for actions that operate on the window. This is actually pretty straightforward since most of the default shortcuts can just be adjusted so replace Alt with Super, e.g., Super+Space to invoke the window menu, Super+F4 to close the window, Super+click-and-drag to move the window from anywhere on the window, Super+Tab to tab through windows. It also helps to dealing with this mentally when you realize that Super maps to the Windows key for most keyboards.
To pull the perspective back, Super+Alt is used for actions with a scope wider than one concerned with the current window, like desktop stuff. Super+Alt+Left/+Right for switching desktops, Super+Alt+F2 for bringing up the Run dialog, Super+Alt+T for opening a terminal, Super+Alt+F1 for GNOME menu, etc.
This has the added benefit of freeing up any combination of Ctrl and Alt to be used by applications. This can actually be a big problem, otherwise; I've run across many applications that assume Alt+Function key shortcuts, which cannot be used since they're bound to some global action in default Ubuntu (GNOME?) installs.
