I posted a short script in c.t.p to do this last month (see "Re: Can
Results From A Search By Adobe Reader 9 Or Another Software Be
Exported?" message-id <7j9s0lF...@mid.individual.net>) which can
give you page and paragraph number.
xpdf (and maybe others) can take a page-number argument after the
filename and will open the document at that page. The script could
easily be adapted to call xpdf with the page number of a reference.
Be aware that "page number" in both the script and in xpdf means the
sequential page number of the document starting at 1 regardless of
whatever digits are printed on the page (because the PDF documents
doesn't know they are page numbers). Unless you use some sophisticated
PDF-creation software that adds "targets" to the document, it isn't
possible to open to the "page number" that is *printed* on a page.
