I can't comment on this, sorry.

It starts with the name of your pcb file, not the name of the project.
Then ".output_" is appended, followed by the name of the group.
Names are shorter if in the print menu, you select "DOS (8.3) names".

That's a normal request by the board shop.  I script the zip
process in a Makefile.  The zip also normally includes a README
file, specifying layer order, thicknesses, contact information,
etc.  I wish for an industry-standard file to associate Gerber file
name with layer, along with constraints on copper and dielectric
thicknesses, and materials.  I guess it doesn't exist yet.
