Anyone know of a Permission helper or canned reports to help if you wanted to do an internal audit of all your roles and the permissions tied to them

What kind of audit do you have in mind? Not exactly a helper or reports, but if you're comfortable with it, you can download all the roles into XMLs by using SDF and then search/compare them. Alternatively, Salto's free-tier also has full visibility into all roles and permissions (including searching, comparing roles, etc.), and is probably easier to use than SDF.
