yes, there is a button in the Scheme window to let you do that

Well, you could pick up the score's file name and add the ".pdf" quite
trivially.

(d-ExportPDF (string-append (d-GetFilename) ".pdf"))

and you could remove the trailing ".denemo" and replace it with ".pdf"
using this

(d-ExportPDF (regexp-substitute #f (string-match ".denemo" (d-GetFilename))
                   'pre ".pdf"))


Your other ideas are fraught with trouble, though - the tagline could
be done

(d-ExportPDF (string-append (d-DirectiveGet-scoreheader-display "ScoreTagline") 
".pdf"))

but here there is a problem of sorting out which folder it will go in -
by default it will go into the temporary directory where LilyPond does
its work.
Likewise you can get the title:

(assq-ref (eval-string (d-DirectiveGet-scoreheader-data "ScoreTitles")) 'title)

(if you are using simple titles) but creating a path to save the PDF to
would require more work. 

Both the tagline and title suffer from the problem that depending on
what you have set them to they may make an invalid file name.
