Today I had exactly the same problem and searched in my archive of
this mailing list for a solution. Now, I only found your posting with
the same question. After searching the GDK "documentation" a little
bit, I found the solution for both problems:

  gdk_window_get_root_origin (window, &x, &y);
  
It stores the correct position - including the window manager
border offset - in x and y. And you get the correct value without
the requirement to move the window first, as well.

Altough I got the same value 22 during my tests, it is not hard wired
and depends on the window manager. If I increase the font size for the
window title (I'm using the Window Maker, btw), the value is increased
too.
