If you want full control, here's a script to convert shapefile polygons to kml, I've just been piping the output of the script to a file, windows: c:\script.py > c:\output.kml. The script also creates a popup and link to a url. If you want separate files, you'll need to open, write to, and close a file on each iteration. Something to start with...Have fun!
