Answer 1

Widget.ids only contain ids of its children (http://kivy.org/docs/api-kivy.uix.widget.html#kivy.uix.widget.Widget.ids. Id of the widget itself it's not needed because you can just pass it directly - in your case using self, since you're passing a reference to a widget from inside of a method:

class Important(StackLayout):
    def NoInspiration(self, smile):
        print("Received: {}".format(smile))

    def AddFancy(self):
        print(self.ids) # only returns {'boxy': <weakproxy at 0000000002D119A8 to BoxLayout at 0000000002D026A8>}
        self.ids.boxy.add_widget(FancyButton(text='f', imp = self)) # no need to use a factory
