New site set up

I have uploaded a new site and now need assistance with setting up the site.

I am having issues with not being able to apply membership information to start with, and I would like to add and apply 3 memberships, plus set up a membership set up module that i have seen module that will allow me to add members, define their allowed actions and add prices and subscriptions.

I also need to remove all dating references to the site and change it to customers and stores as this is a shopping community.

I also need someone to just look at the admin and see if it is working correctly as I get a lot of page stalls, where the action does not go through because the page tries to load and stays in page load mode (yawn).
