Meredith,
I also use standard grads background maps for most of my work, but have
increasingly taken advantage of the new shapefiles capabilities. Attached
script file includes a simple example of using a shapefile to create a basic
background map. There are detailed instructions for using shapefiles in the
GrADS Documentation Index.
Unfortunately, I don't have any experience with google maps. Hopefully
someone else who does will furnish a more helpful response. You might also
check out the "basemap" script which should be included in your library.
Best wishes...
Stephen Mc
