The order the OP shows would NOT be in the Library, which is always Author/Title.
OP You can only control External saves
Be aware really long names can cause issues (Calibre tries to do a logical truncate). But I am curious: Why, don't most devices use metadata and their own bookshelves these days?
Use the Template feature of Send to device or Save to Folder
Code:
{series} {series_index} - {title} - {authors}
