Styling product page in Atahualpa (using WP e-Commerce plugin)

Newbie here!

I am struggling with the styling of product pages. I have created products using the wp-ecommerce 'store' but can't

1. Collapse the too-long product description and thus bring the 'add to cart' option higher on the page

2. Can't set the font colours in the product description and price info. I have been around and about styling inputs on all ATO sections and just can't work out where to change this!

This is the page that troubles me:

Thanks
