A. This would need to be done in our Pro Software.
What you would do is modify the adminpages files for these pages and create pages for the memberships that you don't want to have access to the page.
Then, make these pages completely blank (or put a message saying they need to upgrade).
You would also want to modify the account.php adminpage so that only the appropriate memberships can see the links to go to these pages.
This is something we can do as a extra support request for an additional 200-400 credits.
Below is a document explaining more about editing admin pages:

A. Go to
Advanced Features.
From there it is about half way down under the section "Member Spotlight".
When turned on you have the option to select the member and enter a description. The member's name, profile image, and description will appear on members area home page (/admin) for all of the members. If it does not appear then the code
~memberspotlight~ needs to be added into the html template file for the page located at
/adminpages/index.html
