Multiple Product Page with E-Commerce Plugin??

I have seen posts with this question, but not with the answer I needed. When downloaded ecommerce, every product that is uploaded goes on one page. I know I can make product catgories, but I would like to make a seperate page for each category, with a drop down menu for the sub categories. So the full menu can be listed with the menu at the top instead of as a widget on the side. Also, even thought I have created categories, my uploaded products show up on the products page AND the product category page. Here is my website (which is very under-developed) http://www.homesweethomeboutique.com

Any help would be much appreciated. And I am very new to this, so please know I am on a “kindergarden” level with this stuff.

Thank you so much!
