Steve,

I would suggest you look at:

  http://svn.osgeo.org/gdal/trunk/gdal/swig/python/samples/vec_tr.py

It shows updating the geometries of a set of vectors as part of
copying them.  Then you just need to figure out how to get
the attributes out of th features and passed into the processing
functions.

Good luck,
