First Time at Tele2 Arena - Help!

I'm gonna be flying solo from the states for the shows in a couple weeks. This will be my first time in Sweden and I was hoping you guys could help me out with a few questions I have about the venue.

  1. I'll be out running around during the day and then heading straight to the show. Is there a coat check or anything? I probably won't want to wear a heavy winter coat indoors for a rock show!

  2. Are food and drinks readily available at the venue? I read somewhere they stop serving alcohol once the show starts.

  3. I have floor tickets. How early do I have to get there to get a decent spot? Can you see OK from the back of the floor?

Any help would be greatly appreciated. See you guys in a couple weeks!!!
