For adding the copywrite, you don't have to change the page numbers if you added as Roman Numerals (I.E. i,ii,iii,iv etc.). I've seen than in quite a few books. That way you can keep your page numbers the same and still be able to add more before the table of contents.
Do you want to merge, add to, create PDFs? I have Adobe software that allows me to make one mega file out of many smaller PDFs. If this is what you need, let me know as I may be able to do it for you. You can always reach me by email.
