After removing the 'unnecessary' plugins I would also delete corresponding settings files from the configuration plugins folder - e.g if I removed the Goodreads Sync plugin I'd also delete the Goodreads Sync.json file.

Their presence won't effect performance but if you were to reinstall the plugin next year you would inherit those old settings - which may not work come 2018.

Some plugins store configuration settings in the database, I don't think there's a simple way to remove no longer used library level settings. You could carefully edit them out of the metadata_db_prefs_backup.json file and then run Library Maintenance->Restore database. Two caveats - on a library of 150,000+ books that could take a while - take a copy of the metadata.db and metadata_db_prefs_backup.json files first, in case you break something. See next post.
