I think I solved all my three questions for myself now ...

static PyMethodDef import_hook[] =
{
{"__import__", __import__, METH_VARARGS, import_doc},
{NULL, NULL}
};
Adding the METH_VARARGS solved this, now the __import__ function is
intercepted as well.

By not focusing on the module but using
sys._getframe().f_code.co_filename I solved point 2 and 3 in one go.
I'm still looking forward to comments regarding this issue. ;-)
