To achieve this, you can simply attach the id as a property on the overlay
object:
polygon.customId = 1234;

This is already possible. Firstly, turn off the buttons on the map by
specifying drawingControl:false in the options of the DrawingManager. Then,
you can change the drawing mode programmatically by calling setDrawingMode
on the DrawingManager
object:

You can implement your own custom control on the map:
http://code.google.com/apis/maps/documentation/javascript/controls.html#CustomControls
This control can have buttons with your own icons and tooltips, and these
buttons, when clicked, would cause setDrawingMode to be called on the
DrawingManager object to change the drawing mode, as above.
