1. Here is the circuit info:

It includes maps.
2. Yes. You can get there by car, walk (wastes too much time), or get a bus.
3. You may be able to get one at the circuit. I bought parking late, but don't know about camping. There is a circuit office selling tickets near Parc Expo.
4. You probably would need to book beforehand for this. You may be able to persuade someone, too risky IMHO.
