This is pretty hard to do, but it happened to me a few years ago. I fiddled with it and got the lens off without destroying it, but can't remember how. Take it to a camera store that does repairs. They'll be able to at least get the lens off for a few dollars. As far as the stuck shutter, it could just need a new battery. On the other hand it could be the classic dead capacitor, a common problem of the X-series - a $7 part that costs $100 to have somebody do the work.
Good luck.
