Hi,
It may be good to know that older Geoserver versions can’t utilize external overviews which are saved into separate files (image_name.ovr) if gdaladdo is run with -ro option. I believe that external overviews are supported nowadays but I could not find since which version.
Internal overviews are added into the image files and they cannot be removed or updated easily if one wants to test with different resampling methods so I recommend to take a backup first.

If I create overviews for the images, do the Geoserver layers
associated with it need to be recreated?
Going by memory, to be sure the overviews are recognized, you have to restart
the server, or reload the configuration (the reload button in the server configuration panel)
Cheers
