If both vectors are available as shapefiles, you could put the two shapefiles into one directory (with no other shapefiles in it) and then try something like v.in.ogr dsn=/path/to/folder/with/shapefiles/ type=boundary,centroid With type=boundary,centroid, lines will be converted to boundaries and points to centroids. Attributes attached to sites (points) will now be attached to areas, nothing else to do.
