Terms and Conditions / Vendor items sort OSC

Project1: Need terms and conditions with checkbox so customer can understand terms before final confirmation of order. Make "terms and conditions" link open small window with scroll bar to fit long page of terms. Project2: Also edit Vendor Manager contribution or multiple products manager contribution already which is already installed on site to list/sort all items by vendor. I need to be able to click on each item to view image of item, also for items to have a check box so I can select multiple products and delete, and also be able to edit/delete/move/copy etc.... similar to categories when you have list of items in each category, but I need to sort by vendor. This is so when a vendor sends me a very long list of discontinued items I can sort by vendor and click the box or select all and then delete. Or if a vendor sends me a list of items that have added new colors, I need to sort items by vendor and go into each item to edit attributes.
