Cloud Zoom Replacing Lightbox + others

The changes I need are quite simple - 1. Get cloud zoom to work, and disable the current light box on product images. I've only set up one complete product so far for you to see. That link is [login to view URL] . I want the cloud zoom to match this example [login to view URL] , where the image zoom is directly on top of the original image and where you can cover your mouse over the thumbnails and it switches over the larger image without needing to click. 2. Product page images need to switch on hover. Just like this example http://www.thegrandsocial.com.au/index/t-shirts&gender=man where you can hover the mouse over an image and it switches to another one. Not sure if this is something you can implement in the backend of BC where I can just select the 2 images I want to switch between. 3. The NEWSLETTER sign up form on the bottom right of the page doesn't work. Always comes back with an error when users click Sign Up
