You want to change the title permanently in your calibre library, adding the series name and number? One could debate whether or not this is a good idea. My opinion: it isn't.
Assuming you really want to do this, select the books you want to change, then use edit metadata (bulk), search & replace. Use regular expression mode so you get the advanced options. Choose "template" as the source, provide a template that produces the output you want (it will be like the plugboard templates), choose "title" as destination. Check the samples to be sure you are getting what you want. Press OK and wait a while. Changing the title requires moving files around on the disk, and this can take a long time.
