Oscommerce custom specials page updates and product page fix

I have a customized sales page that is currently working fine but I want to make some updates to it and I ran out of time to work on it personally. What needs to be updated is the following: 1. I have added a field in admin for MSRP price. If this field is not blank and the special is active the MSRP price should should (crossed out) on the following pages (category, sales page, search, Product page, Shopping cart page). This should not affect the 2. On the sales page and the product info page, if there is a sale going on I want there to be a countdown showing how much time is left for the sale price. All times will be set by day (12 am ending) but the timer should show hours left. 3. In the shopping cart I want to have a "you saved" sub total so that it shows the sale price subtracted from the MSRP price. 4. currently the javascript is loading images twice on first load of the product pages. You can see this here: [login to view URL] Notice the first time you load the page you will see the product images duplicated and on rollover it is the incorrect image being shown. If you refresh the page it works properly.
