I did this with Connectors. It's my one change to base class methods.

Morph>>
addedOrRemovedSubmorph: aMorph
	aMorph fullBounds.
	aMorph changed.
	aMorph noteNewOwner: self.		"this line was added"

So this notifies morphs when they're dropped into something else.

As far as notification upon addition, you can subclass 
addedOrRemovedSubmorph: for the same purpose:

MyPasteUpMorph>>
addedOrRemovedSubmorph: aMorph
	super addedOrRemovedSubmorph: aMorph.
	aMorph owner == self ifTrue: [ "just added ..." ]
