524335 Pinnacle Cart Expert Needed

I have a claimtheweb ecommerce site based off of pinnacle cart. There are several things that need to be changed.. 1.) I am no longer working with a distributor who is supplying my products, so I need to put in a 301 redirect to the homepage for all of the current products. Products are dynamically generated so you shouldn't have to manually edit each product. The htaccess file already has a rewrite rule so you will add to that. 2.) In pinnacle cart, 22,000 products are listed..I want to delete all the products either manually or through the database. When I try to delete a product manually through the cart software, I receive an error message: Fatal error: Call to a member function deleteRecordsByProduct() on a non-object 3.) There is a resizing problem with the products. When I click on the product picture, it will not increase in size. 4.) Currently, it's listing the description of the product as well as the related products right next to each other. The user has to click on the related products in order to see the products. I would like the related products to be listed underneath the description box. So there would be a description box and then below that would be the related products box. 5.) When I add a product to the cart and then go to the checkout page, once I close the browser a popup will appear stating don't leave. I want to disable this popup. 6.) I have a new datafeed with a different distributor that needs to be implemented..cron job may be necessary as well. (This part of the project would be completed last) I am looking for a long term working relationship on this site.
