This one also contains a tutorial on how to make the display shelf. (coverlfow / carousel)
This link was AWESOME. I can't believe I didn't find it on my own. Its for a coverflow, and not a carousel, but its all done with off the shelf spark/mx/flex components.... No papervision3d or flexlib or anything. Thanks!
Here's the carousel layout : http://www.ryancampbell.com/2009/06/16/heres-5-3d-layouts-for-flex-4/
Programmed a free 3D Carousel wich uses the Flex 4 Layout Framework. Maybe you wanna have a look: http://webverwirklichung.com/en/blog/programming/flex/3d-carousel-layo ut-flex
