How can I create an XFDF file from a PDF either
1) using Acrobat 8 Pro; or
2) using open source tools
I tried creating the XFDF by hand, but I'm not able to merge it back into the PDF. I presume it's because it is a multipage PDF form. That's why I'd like to generate a working XFDF file as a template.

Load your form in Acrobat 8, fill it and the select in the main menu Forms > Manage form data > Export data and choose XFDF format. The XFDF file content is not related to the number of pages in the PDF form.
