Answer: ISO 27001 does not require you to include users of the procedure, however it is easier if you do write this because then you know who to send the procedure to.

If I put "Approved By: ***" (which are my presidents initials) do I have to have him sign them? Or will that be sufficient?

Answer: I'm not sure if I understood your question correctly, however when you write documents you should include their revision number and date; if you want you can add a code to each of your documents; when you refer to other documents, you do not need to mention all these details since this would mean when you change one document you would ne ed to change all the related documents, too.
