Categories and Article Problem in Upgrade to Responsive Framework

I upgraded from the Real Estate standard theme to the new responsive Real Estate theme. The non-responsive theme had an Article Manager with article category pages listing the various articles in each of the categories. It also appended the category name to the url’s of each article post.

In moving up to the responsive theme, I find there is no Article Manager and I don’t know how to duplicate the url structure. I want to do this in order to maintain my indexing of the existing pages with the engines. I also would like to recreate an environment where I can have category pages listing all of the articles for each category.
