Need more whitespace between product listings

I'm using the latest version of Zen-Cart. My site is http://www.herbalaxation.com.

The page I am asking about is this one: http://www.herbalaxation.com/index.php?main_page=index&cPath=2.

The products are all squished together. I'd like to increase the white space between the products but I do not want to totally screw up my site. I am thinking that padding can be added to a class or ID in CSS to achieve this? I am just not sure where to put it.

Also I wish to remove the home link that is sitting on top of my background on the home page. I am not sure where to go to remove this.

Thanks for any help you can give :) Take care!

Try adding this to the end of your stylesheet.css file

.productListing-data {
        padding: 1.5em 0em 0em 0em;
        }

Worked like a charm!!!! Thanks so much!!! 

Now I just need to find a way to make my header_bg.gif graphic into a link for the home page...either that or use it as the logo and not the background, though I'm afraid that will screw up many things...
