I use this website to order GCMS note:
https://caipsnotes.com. It said within 30 days, but in reality it only took me approximately 14 days. If you want to see what GCMS note looks like, I can let you my screen cap just inbox me.
I think you might need to wait a little bit. Consider this case:
https://www.canadavisa.com/canada-immigration-discussion-board/threads/study-permit-rejected.696227/. Despite of holding F1-OPT (file case pending), this person was still rejected for study permit regardless of attaching valid status document along with the application. I think you may wait until there is a start of reviewing the eligibility in your application. For your questions, if you answer NO, the inquiry will go to CPC Office in Canada for response. Given you are living in LA, the best option is to say NO to that. The webform will allow attachments. I remember it allows up to 2MB document in pdf, jpg... format for attachments.
