Multiple permission/security levels

Hi, I’ve taken over administering a WP website with S2 free installed. The site works well but I need to add more pages but with additional security. The site works with free access and member subscriber access.
I need to create new pages that will be available to members only but members who purchase extra options (i.e. sing up for specific training course).
All current members security is set to Level 1 or higher.
For this new functionality I think I would like to add the role of Event Contributor to some of the membership.
For these new roles how do I test for this whin the new pages? I am unable to see anything along these lines when I am building the pages.
How do I do this?

Maybe best way will be to use ccaps.

As I am not a coder I have searched for a user guide on ccaps and am struggling, even on the WP documentation pages, can you offer some guidance.

Read the s2M setup pages, there is lot of info inside. Read all Paypal related pages, there you will find ccaps. Do some tests as well, you will understand much better.
