Minor changes to a WordPress site

I have a wordpress website rate-my-car-dealer.com.

It has an etension installed on that turns it into a business directory site.

I have purchased an extension to that plugin that turns it into a yelp style review site, i need that extension (I will provide the files to you) installed and setup.

Also if you go to the homepage of the website, it still has the standard wordpress homepage setup on it, i need the homepage to look and feel more like a yelp style review homepage (I believe there is a standard on in the extension that will work fine, just need different more relevant graphics)
