        <%
        %>
    </script>

Answer 1

I am not sure of what exactly the question is.
Are you asking about how to access variables in JSP ? Or how to pass a parameter from an HTML page to a SWF ?
Here:
           'meetingModule.html?roomURL=<%= roomURL  %>&authToken=<%= token %>',
you are simply passing variable to the HTML page. From there you need to use javascript to parse the query string and pass the values to your SWF.
If you look at the ExternalAuthentication examples they all do something similar.
