My question is: I have existing PDF files. I need to merge the files and add page numbers to the bottom of the files. With the components I have, is it possible to do what I need?
You would need WPViewPDF Plus. The stamping facility can add page numbering to existing PDF pages (in the manual: Use stamping script - COMPDF_StampText)
You can upgrade a single WPViewPDF PLUS license to PLUS using this link:
