Pro Sites & membership - What am I doing wrong

I need some hand holding I think as I'm going round in circles and have been for weeks now.

What I want to set up is a multi-site with marketpress and a host of other plugins available to select levels of membership. Now I chose pro-sites as it would allow the creation of sites and dictates which levels get which plugin access etc.

Problem is I have three levels:

Level 1 = Free basic site
Level 2 = Basic site (paid subscription)
Level 3 - Pro Site (paid subscription)

Level 2 & 3 work fine but the free level I am getting confused at. Attached is a screenshot of what a member gets to once they have registered and confirmed. I need the free level to enable people to go straight through to their admin panel so they by pass paypal.

How do I do that?
