How to change all links in each product to external links?

Using the framemarket theme on the front page, I have the Buy Now button linking to an external site.

Is there a way to make the product name AND the product image go to the same external site as well?

Also, which link redirection plugins work with framemarket? I would like to hide the fore-mentioned external site/URLs like this: http://wpmudev.org/visit/234 with the each link going elsewhere.
