I was able to achieve this by simply doing the following.
1. Deleting, the intermediate.php file from CSSMenu directory.
2. In the following five .php pages editing out this line
<?php require_once("CSSMenuWriter/intermediate.php"); ?>
from: Product_Results.php, Product_Detail.php, cart.php, checkout.php, Products_Search.php
This will produce the results of products on right hand side of page, no products or categories on left hand side of page. I hope this helps anyone else that's been waiting for this answer.
