Welcome to MobileRead, Grahame66. I hope you'll get lots of usefull advice here.
I am not sure I've fully understood what your problem is.
In case you need to change PDFs metadata check this out:
BeCyPDFMetaEdit
It's a powerfull free tool (mentioned in several threads in MR) which allows you to change author, title, and a few other things in PDF files.
