Thank you! If someone had told me earlier that my question was incomplete, I know I could've saved you all a lot of grief.

1)Yes
2)Yes
3)If there's no series, then I want it to simply display the title in my Kindle exactly as it is in the Calibre Title field.
4)If the index is zero, then I'd like it to display the #abbrseries value as usual, with a leading 0 in the tens place (eg "HGTTG 00 - ...")
5)If it has a decimal point, then I'd like the new title to reflect that (eg "HGTTG 05.1 - ...")
6)Just the plugboard is fine. This whole thing started because kiwidude recommended that i unclutter the Title field in Calibre (ie, strip out the series info that I'd input).
7)Not that I can think of.

Again, thanks for breaking it down for me.
