Bob,

I did something like this recently but did not find a way to do it 
without writing a short script or two.  Here's what I did.

I put the polygons in a postgis database (which I needed to do anyway to 
do some overlay operations).  I output the polygons and their centroids 
(for the labels) as separate kml files using ogr2ogr, and I wrote a 
short script to combine those two kml files into one kml with the style 
and labels set up the way I wanted.

In the end it might have been easier to script the whole thing (skipping 
the ogr2ogr part) from one postgis sql that output the polygon and 
centroid in the same record as kml.  Were I starting from scratch I'd 
try this approach, but I already had a script written to combine 
multiple kml files into one.

Hope that helps.
