Steve, In the early days (ie. Up MapServer 4.2 or so) MapServer did not honour non-square pixel requests. It would basically adjust the extents of the request to force the pixel size to be square. This was fixed in MapServer 4.4 (or perhaps 4.6?) I don't have anything to add on the Google overlay business.
