There is also some good information at the old api group:

Here is the code from the first link:

UI.menu("Plugins").add_item('Make Sang Red') {

  # Assumes that sang is the 1st entity in model.
  sang = Sketchup.active_model.entities[0]
  sang_def = sang.definition

  # Override sang's shirt color to red. ("material"
  # is a special attribute that requires
  # you to set a formula to "take control" 
  # over the default material the user has painted.)
  sang_def.set_attribute 'dynamic_attributes', 'material', 'red'
  sang_def.set_attribute 'dynamic_attributes', '_material_formula', '"red"'

  # Add a new configurable option to Sang.
  # (Any attribute that starts with an underscore
  # is a "meta attribute" that describes behavior.)
  sang_def.set_attribute 'dynamic_attributes', 'weight', '145'
  sang_def.set_attribute 'dynamic_attributes', '_weight_label', 'weight'
  sang_def.set_attribute 'dynamic_attributes', '_weight_formlabel', 'My Weight'
  sang_def.set_attribute 'dynamic_attributes', '_weight_units', 'STRING'
  sang_def.set_attribute 'dynamic_attributes', '_weight_access', 'TEXTBOX'

  # Change the description that shows
  # up in the configure box with a custom
  # formula.
  sang_def.set_attribute 'dynamic_attributes',  '_description_formula', '"Sang is now red and weighs " & weight'

  # There is a global handle into the plugin that
  # allows you to make the same calls that the
  # plugin does, like so...
  dcs = $dc_observers.get_latest_class
  dcs.redraw_with_undo(sang)

}
