Looks great. Names can be declarations or references. You might want to
make sure you don't process the references, or the forward declarations.
I'm not sure, but I think a class definition would mark the name as
isDefinition() == true. Also, you should always use the public
interfaces provided, e.g. ICPPClassType, so that we can change
non-public methods on you :)

You are correct. We should look seriously at getting a wiki setup for
the CDT so that people like yourself can easily share tips like this. I
know eclipse.org is looking into something, I'll check with them.
