User Registration, Profile Completion and Profile Listings

Greetings,

I am looking for an appropriate plug that will do this:
– allow users to register and login to a site (while unregistered users can still browse the site, but limited to non-restricted pages);
– allow logged in users access to certain restricted pages that are not accessible to unregistered browsers;
– allow logged in users to update their profiles on a restricted page (updates being submitted for authorisations);
– publish profiles in a directory format, that other registered users can see on a restricted page.

What are my best plugin options with the power to do this?
