I never used drawBackground
but I think that you have to re-implement it in your class

like

def drawBackground(self, painter, rect):
    ...

about layers, I think you should look at "parent".
you can create an item, and specify its parent (will be another item).

for exemple, one graphicsItem can be a blue rectangle.
and then, you can create 10 other items (like circles, or something else),
and set the blue rectangle as parent of circles.

in a way, you have a layer.
