RE: will I be able to retrieve the information from my existing registered users and add them to the plugin?

Sorry, no. Generally a WP User account does not contain enough info to create directory entries since the user account only requires a username and password. Connections requires at least a first and last name. If you users contain their first and last names, then you could use a WP User CSV Export plugin to export the info and then use the CSV Import extension for Connections to import that CSV file.
