Anyway, it may not be the answer you want but there are other tools on the market for meeting these demands.
For automated bookmarking of doents, perhaps it may be worth checking out the demo of ARTS PDf Bookmarker, <http://www.artspdf.com/arts_pdf_bookmarker.asp>.
For converting TIFFs to PDF in batch, ARTS Import, <http://www.artspdf.com/arts_import.asp>.
There may well be other solutions out there.
Hope this helps...
