Some comments 1) I think the inline views FA and DF can be merged, as they use the same selection and grouping criteria.
2) I would suggest to include free_total_no_auto and percent_free_no_auto columns (I assume it is easy to guess what the names mean). Personally, I want to avoid letting the data files autoextend, in order to avoid fragmentation blahblahblah, but I would allow one file per tablespace to autoextend, in case I can't reach the database to add files for some period of time (e.g., caused by bad weather or bad health).
