Products Listing beef up?

[SoniCraze]

I was wondering if there was a way to get a more detailed products listing, maybe with a little 30X30 pixel image.

 

something like http://pcclub.com/product_list.cfm?cat=CPU...on%20Socket%20A

 

Also i want to do sub-cat. like they have, for example you click CPU then you are presented with a file tree of options.

 

Any way to do that? I learn quick. :-D
