I want to change the look of the auto generate Store page

Aloha, I'm using the Echo Theme for the Rumley site that I'm working on. I purchased and installed the MarketCommerce plugin to get support for ecommerce. I'm wondering if there's a way to have a theme other than the available echo's themes for the auto generated Store page? If you take a look at the page that's created you'll see that it's boring as heck. If you click on the Products link you'll see a basic page that lists all of the products that I've defined. I'd like to make the Store page a bit more exciting and if I have control over the look and feel of the Products page that would be cool too. I'm a new Wordpress user so I'm not the best developer for this but I'm doing my best to make this all work seamlessly. What do you think?
