The application only requires copies of the biographical pages.
If you wish to, you can include copies of stamped pages as well. In my case, I was about to do so, but then realized I have stamps that are not in English or French, and if I didn't provide translations it may just backfire and give them a reason to return my application so I chose not to risk it. Sometimes overcompensating can come back to hurt you. I believe they look at the passport during the interview on the test day anyway.
