Featured image and Customer Reviews

I’ve just installed this plugin and have some questions about how it works:

1. I’m using the twentyten theme which uses the ‘featured image’ as the header. This interferes with the featured product image. I’m happy to input the image in each product description, but that leaves a large space on the main category listing page. Can that be removed?

2. I’d like to include customer reviews with each product, can this be done, or is there an extension for this?

Here is a link to the homepage of the website: http://www.servicesinaction.org/

Thanks so much for your time!
