Look for Chaley's post in this thread for a simpler approach
Or dwanthny's post in this thread
I use this plugboard (from Jackie_W I think)
format device_db
device any device
source template {author_sort}{series:| - | }{series_index:0>2s}
Sony device interfaec Plugin is set to
save template {author_sort}/{title} - {authors}
collection field author_sort
This gives me a collection for each author with the books sorted by series. After the authors name for each book the Sony shows the series name and number
