making New Products Listing look like Category/Manufacturer Listing ??

Hi all,

I am new to Zen-Cart and perplexed by the product listing engine, and how it looks depending on where you're at in the site.

It seems like there's 2 main listing engines:

1. that is for New Products and Featured Products, that has lots of white space and is configurable in the Configuration menus. no problem there

2. and another that is for Categories and Manufacturers, which is displayed in a table format with the orange bars (by default). I cannot find where to configure the layout/look of this listing system

You can see these in action by going to my test site: http://eddies.dreamhosters.com and clicking on New Products, then click on the Guitars category, and compare the 2 listing formats

I guess my question is:

a) is there a way to make the 2nd listing format look the first one, or if not:
b) is there a way to customize the 2nd listing format??

thanks for any help! sorry if this is in the wrong forum
