gnome-core already has a dependency on metacity.  However, I didn't
install metacity or metacity-common from experimental, so I didn't have
a version of metacity-common with the gsettings schemas until May 30th.
The window manager keybindings seem to show up now.

Might I suggest changing gnome-core's versioned dependency on metacity
to (>= 1:2.34.3-2)?

(Also, why does gnome-core depend on metacity, given that GNOME 3.4
doesn't actually use metacity, just metacity/mutter's libraries and
such?)

~$ gsettings get org.gnome.settings-daemon.plugins.media-keys www
'<Super>b'

Looks like the bug report below regarding <Super> handling explains most
of this bug.  I've retitled this bug accordingly, and cloned it for the
other issues.

Both; I'd defined some new custom shortcuts and also assigned keys to
predefined shortcuts:

~$ gconftool-2 --config-source=xml:readwrite:/home/josh/.gconf.shared -R /apps/metacity
 /apps/metacity/window_keybindings:
  move_to_side_e = <Super>Right
  move_to_side_s = <Super>Down
  toggle_maximized = <Super>m
  move_to_side_n = <Super>Up
  toggle_fullscreen = <Super>f
  move_to_side_w = <Super>Left
 /apps/metacity/keybinding_commands:
  command_1 = firefox -new-tab "about:blank"
 /apps/metacity/global_keybindings:
  run_command_terminal = <Super>n
  run_command_1 = <Super>b
[...]

Now that I've upgraded metacity and metacity-common, some of the
shortcuts I want to set have shown up again.  None of my previous
settings appear to have migrated, though.

That bug report makes the issue pretty clear.  With the window manager
catching the <Super> modifier and using it to open the activities
overview, nothing other than the window manager can use <Super>+key for
shortcuts.  So, all the <Super>+key shortcuts in gnome-settings-daemon
(such as launching a browser) don't work, but those in the window
manager (such as moving windows around) work just fine.

Now that I have the proper version of metacity-common installed,
shortcuts for maximize and fullscreen show up again.  Shortcuts for
moving windows up/down/left/right don't exist anymore, though.  However,
while I don't see them in the dialog anywhere, <Super>+left and
<Super>+right now maximize windows to the left and right halves of the
screen, which works nicely; <Super>+up and <Super>+down got mapped to
maximize and restore, which work for me.  So, I don't actually need the
window movement keybindings anymore.
