Covenant with Allah

I have a couple of questions regarding the amazing event that took place which is mentioned in Ayat 33:72 of the Quran:

Does Ayat 33:72 say that all Human beings took the covenant with Allah, or just Adam (pbuh)?
and did this occur before Iblees tricked Adam (pbuh) or after it?

Also does anyone know where i can learn more about this particular covenant? is there another Ayat in the Quran about this?
or any article or lecture discussing this moment?
