Access at different membership levels

Hi, I have the membership plugin activated, as well as buddypress, the directory and classifieds.

I want to restrict access for users on particular membership levels so that they cant list on the directory or post classified ads, but even though I have changed all of the access levels and permissions the ability to post in the directory and classifieds still comes up on the users profile page.

Please help, am I missing something?
Also, I don't appear to have search links etc on my directory page, is this because I need to add in short codes for buttons? (the page is not editable)

My website is http://adelaidehillsholistic.com.au

Thanks,
Venessa
