Start by making the page look correct. Then try to add the functionality.
The reality is that it may be difficult to do this without at least a small amount of hand code. Regardless Webassist tools won't help you make a page that looks like that.
You will need to use Dreamweaver Recordsets, Repeat regions, and forms in conjunction with a database in order to create a page that looks like that. Once you have it looking the way you want then you can start worrying about how to add the checked items to the cart.
