Hi Jeremy,
Do you mean that you want to restrict users from an action, for example creating events, but at the same time you want to provide the permission to do so to admins? If that is the case, you can assign the admin users to another profile type and enable the create events permission there. This way you can turn off the events creation permission in the default Registered users profile type.
If this is not your issue, perhaps you can elaborate more on what actions you want to limit to regular users so I can better advice you, thanks.
