I like section 203/204 because you are far back enough, but central so that you can see everything happening and it won't hurt your neck looking up at the action.
Yes, it is worth the money. My family and I saw it twice and loved it both times. It's something different and fun.
I think the show is 2-2 1/2 hours with no breaks. You can probably enter at least 30-45 minutes before it starts. Try to come early because there is a fun pre-show (I think the pre-show is 10-15 minutes before the real show starts)
If you are really curious, you can watch the show (from the DVD) on
youtube.
