Getting the URI of original PDF would be straightforward enough - I could whack that into the code tomorrow with a few lines.
Opening up the correct page? I don't know of any standardized PDF reader that supports that kind of thing. And the format has such a history that even if it were supported (technically by Adobe - don't even get me started on what PDF readers support what formats), there's no guarantee the file itself would even have that cooked in.
