I wa confused about the attribute "required" in field and field set.

If an field is defined as required, will it be required without any configure in field set?


 

Is it possible to add access control for Field Set？And is it possible set the ordering of the row data in Field Set?

My usage is to provide a field set which include the fields that user want to get via metadata API. But only parts of users can access the field set.
