I have had major issues with the GridMarket theme

I have had major issues with the GridMarket theme on a network site. The site is at http://thingsmywifemakes.com/itsespecially4u. You will notice that the main page shows the product list, the images however are being cut off. I would really just rather them display as they do by default, like in the category view but this display is even worse yet.

This whole mess started when I went into the Products admin>Presentation and clicked save. I did this so that I could create another page, about-my-products, which does not show up unless you set the home page to Store and posts page to blank.

At any rate, can someone look at he site and give me some suggestions, I am ready to delete the whole network.
