It should iterate over every interface in the .idl file - see 
BuildOleItemsFromType in genpy.py (and maybe some "print debugging" in 
that file will help you see what is going on)

Nope - as it shouldn't skip them in the first place.

win32com will help you a little here - assuming the interface is 
generated, you could say something like:

mod = win32com.gencache.EnsureModule(...)
obj = win32com.client.Dispatch(...) # get default interface.
obj = mod.SomeOtherInterface(ob) # convert to SomeOtherInterface

This works due to the __init__ method generated for the interfaces (it 
does a QI - see the generated code for details)

HTH,
