Personally, I rather dislike disturbing the title and title sort fields in calibre so I use a "Save Template" template for the file name and a plugboard for the internal title.

These are set in preferences. You should set a Save Template in both the "Save to Disk" and "Send to Device" sections. This way only the file saved to disk or sent to the device has the altered title. The copy in calibre's library still retains the standard title and you leave the series information in the Series field.

The template I use is:

{series} {series_index:0>2s} {title} - {authors}

The prepends the series name, a space, and then a 2 digit series number with a leading zero when necessary followed by another space.

The plugboard is similar but uses two lines:

first line:
source template: {series} {series_index:0>2s} {title} - {authors}
destination field: {title}

second line:
source template: {author_sort}
destination field: {author}

The first line changes the internal title prepending the series info. The secont replaces the author with author_sort so that my K3 sorts properly (read: sorts by last name) when set to sort by author.
