Posting to Wordpress pages (membership)

I have been search and I am not able find an answer to my questions. Can you please help? I am trying to use Membership.
1. How do I post to a Premium content page?
2. How do I post to a Free content page?
3. If all posts (premium and free) appear on the main page, how do I restrict viewing to non-Premium members?

Thank you.. I greatly appreciate it!
