That's a nice theme. I'd like to see the finished product
As for the spinning images, you MIGHT be able to do it with Adobe Flash but I'm not sure. The way I'm just working it out in my head is to get the default image for the marquee/screenshot, use that in Adobe Flash and make a short loop of it doing it's thing (quick rotation etc).
I'm not sure if this would work, but you could always try. I don't know (from memory) if you can replace those two images within the theme editor with .flvs. Always worth a try though. Let us know how it goes.
You can get a 30 day trial version of Flash from their site. Should be enough for you to just try this out. Good luck!
