Customize Uploadify jQuery upload and form on site

We have a website that is php/mysql based. We currently already posess the ability to register user accounts and allow people to log in. We need to customize the uploadify file upload system to do the following once people log into their accounts: 1. Allow users to upload multiple photo files at once (it does this natively) 2. When the user begins their upload it will create an "order", which will be a unique id stored in the database. 3. Once uploaded, click "next" and add a note for each photo in a textarea. A thumbnail of each photo must be shown. There should be 1 common "save notes" button/link that will save the note text via ajax/jquery. 4. The user should be able to get back into the "order" and add additional photos to the same order. I can handle bits and pieces of this and will be able to help on parts, most of the help will revolve around the uploader part.
