Yeah, there's tons of pictures of the new tracks. I would direct you to AltF8's site, but it doesn't appear to be working at the moment. You can also see them in some of the videos here.
And, yes, the Monaco track is the exact same one used for the GP!
I saw the video of a RUF doing the Complex String, and personally I'm not excited about it. But the best and most popular will be Special Stage R5 WET.
