PHP / Ajax form in popup on click

I have a contact us form on a webpage, that I would like to open in a popup window (jQuery Modal), with the form appearing in that popup window, and the background page faded out slightly. This is to occure when someone clicks an A href link that says "request more information". When the link is clicked, it should pass through the product name to the form that already appears on the page and also pass the product name to the popup window so the product name is already filled in. When the form is submitted, the popup window should display a thank you message for around 3 seconds, and then close, or will close when someone clicks the X to close the window. The popup window needs to work in IE 7 and above, Firefox, Safari etc. The form and form checking already exists and will not be required to be reprogrammed.
