AS3 XML thumbnails, dynamic text fields, new movieclips

I’m hungup on a project - the overall idea is to build a thumbnail scroller that reads all it’s info from an external XML file. When you rollover a thumbnail, an info movieclip fades in and displays more information about that thumb, and on click it goes to a new URL.

I started with a thumbnail scroller tutorial(sorta) from here:
http://www.flashmagazine.com/tutorials/detail/scrolling_photos_loaded_dynamically_with_actionscript_3/

The design mockup is here.

I’m pretty new to AS3, and don’t understand how to create the info movieclips with their dynamic text fields filled in by the XML, while in a loop. Or how to set the getURL to the right path. I just know I should probably add it in the Thumbnail.as class

The zip file has the sources. Any help would be super fantastic awesome. I’m supposed to meet a deadline by tonight and I’m beginning to get a little panicked.
