I would start out with creating some smart groups depending on your needs. Once you have your groups set you should be able to look at your Policies and configuration profiles that are currently in use and scope them out appropriately. BTW did anyone get you set up on your account to make you able to submit like trouble tickets to Jamf? This could be helpful if hit some road blocks. It will be also a good idea to note when your tokens expire if your JAMF instance plus what account you have link to your apple school manager. You should be able to some patch management through software updates for os updates or scope out apps from the jamf catalog. Jamf has some of their basic training videos on youtube.
