Yes, there is, however, you can get a passport for $35 to visit attractions and it's included in there. It's a great value.
The museum is well worth every penny. Its small but there is a lit of great history to explore. By the way the Olympic Center itself is free to explore but they also have guided groups which are well worth it. Enjoy your visit!

Two of the stadium access is free but rest of the place has a charge.
Yes, its around $10.
