Iconified Windows, and Workspaces

If I iconify a window, is there a way to move the icon to a different
workspace? If the window is not iconified I can use the mouse to do this
by dragging it on the workspace map, but if it is iconified it is not
visible on the workspace map.

When windows are iconfied is there a way to arrange them automatically,
and with no text? The text can be very long for example with Seamonkey.
They are placed at random not very intelligently, i.e. sometimes half
off the screen, sometimes on top of other icons.
