I would like to suggest that you place the generated files in a
subdirectory so it does not get mixed up with the original files.

You can certainly do this with GIMP + Python or GIMP + Script-fu.

"
       --batch-interpreter <procedure>
               Specifies the procedure to use to process batch events.
The default is to let Script-Fu evaluate the  com‐
               mands.

       -b, --batch <command>
               Execute  <command>  non-interactively.  This option may
appear multiple times.  The <command> is passed to
               the batch interpreter. When <command> is - the commands
are read from standard input.
"
from gimp man page.

That addresses your first two points. for the last point, use the
procedure browser to look up file-jpeg-save.
