If you used v.in.ogr with the default settings, there should not be
artefacts such as centroids outside areas. Can you provide the command
you used to import the shapefile and the full output of the command?
That would help to find out why there are centroids outside of any

What exactly do you mean with "remove islands"? You can try the
v.in.ogr option min_area or afterwards remove small areas with v.clean
tool=rmarea which would also remove small holes in polygons.
