A few wordpress fixes

Here is the url in question. [login to view URL] I recently updated to the latest version of wordpress and this screwed up a couple of features on the site. If you know how to rollback to my previous version that would save some time else I need these problems fixed. please provide your solution. Here are the problems. - The image on the top of the page next to the video is supposed to be a slider where it slides between several images. Now it only shows one static image. - On the left column there is an accordion style navigation. Right now they are all open showing all of the sub links. The sub links should only be open when you click on a main category and the they should close again when you click on it again. - We are using a plugin called wp-ecommerce. Right now we cannot cannot upload any images of the products. When I click on upload image, it does not bring me to the gallery, it just stays on the main page.
