To get the IHTMLWindow2, you can just use self.parentWindow
inside the event hander, and then get the event from it.  And then
the event's srcElement should be what you need.

class Doc_Events(doc_mod.HTMLDocumentEvents):
    def Ononclick(self):
        print 'onclick'
        ev=self.parentWindow.event
        src=ev.srcElement
        print 'tagName:',src.tagName,'name:',src.getAttribute('name')

For clicking on google's input field, this yields
tagName: INPUT name: q

PumpWaitingMessages is just a way to ensure that normal message processing
(window messages, events, dde, etc) happens while python code is running.
Normally you don't need it, but every once in a while you hit a situation 
where
blocking occurs.

For how exactly python interacts with COM, the source is your best bet.
