It's late and I can't figure this out

Just upgraded from 1.2.6 to 1.3.7 for a client, everything is going well, but I am having trouble with the CSS page(s).

Using the Template_Default CSS I was able to configure everything I wanted, however the links are white because of the colors they show up in.

The problem is that my background for the main section of the page is also white, so I want to have those links show up in a different color, and then change to yet another color when rollover happens.

I tried this:

.productListing-heading a:link {
color: #ffffff;
}

.productListing-heading a:hover {
color: #ff0000;
}

But that didn't work by putting that in either of my two CSS files (classic and default)

Would love a point in the right direction if someone can help me

here is the page/storefront I am working with
