Going to a Japanese seiyuu event as a foreigner

Okay, so I guess the title says it all but here goes!

I'm going to Japan next weekend to stay there for pretty much a week. Aaaand, the main reason for me going there is because I'm planning to attend this(Yes, i DID get my hands on a ticket) event called Attack on Sound Experience. It's a seiyuu event which will be held in Yokohama Arena, and as my first experience with such things there are obviously some things I'd kind of like to know:

1. The LINES-UPS. It would be REALLY good for me to know how early I should be at place not to risk getting too far back in the line-ups.

2. Are there usually like signing stuff included in these events? Because if there are, I better bring a small pin-up poster or something...

3. The audience. Is there a special way we should act? Like, is the japanese audience kind of... calm? I HAVE NO IDEA! >_<


This is also my first time going to Japan in general so I'm really nervous about it! I do know some Japanese, and my understanding is quite well so I don't think things like that should be an issue... hopefully.


Please help me out!

For the first time you have to be very brave to start with event, I don't know much about the event you are planning to go but being polite and having a look how locals act is a great help.
