To load shapefile data you need shp2pgsql and pgsql2shp to dump vectors 
to a shapefile.

Not sure what you really want to do here. If you mean to render the 
vector data onto into map images. Then you need to read up on Mapserver 
and these might help you get started:

http://mapserver.gis.umn.edu/docs/reference/vector_data/postgis
http://mapserver.gis.umn.edu/community/conferences/MUM3/workshop/postgis/

You probably need to explain specifically what kind of overlay analysis 
you are looking to do.
