Yes. You can turn off a lot of those modules in the admin section, or, if you're like me, you edit them out the template files once you're 100% you won't use them.
Check out my site:
http://shop.viosport.com/ to see how mine looks. To see the store, click "products" on the top nav bar. Is that kinda like what you're wanting? That's X-Cart 3.3.5 in there, just severely revamped.
Hope this helps!
