Questions about an upcoming Lights concert?

[LC]

I bought tickets to Lights concert at Theater of Living Arts in Philadelphia. It's my first concert and I have some questions. They are in order of importance and I would appreciate it so much if you could answer these!:

My ticket says standing room, but I have a seating number. Where do I go if there aren't any seats? Can I move around or would I get in trouble?
Can I ever get close to the stage?

Can I use my camera?

Can she sign things afterwards or before the concert?
Is it possible to meet Lights after the concert (I see many fans have pictures with her) and does it cost anything?

Is there anything I should or shouldn't do?
Should I wear earplugs before the concert actually starts?

How early should I arrive at the concert (she isn't all that known in America and Philly is about 30 - 60 minutes away from me)? I want to get there early, but I don't know how early is TOO early.

It'd be a big help if you could answer some!

By the way, I am going with 3 other people (including parents) and the concert is at 7 o'clock.

Okay, you should always go earlier, because the line-up will be long, and people will fill the seats
I always make sure I'm at the show an hour, even so there will be about 50 people+ standing in line, especially if it's lights.

Yes, you are able to take in your camera, you should call to check or check the website because some venues won't let you. (But that's usually for huge superstar artists) XD

You need VIP tickets to get backstage to meet her..
You could also wait outside backstage.. sometimes security guards will chose random people to bring in, or she'll come outside and see you all.
I bet even after the concert, if you're quick you can probably catch her coming outside.

You can do what I do when my favorite celebrities come into town, I watch their twitter to see where they're at. /stalker grin

Earplugs? really? XD It won't be that loud unless you're right by the amps.. but if you have sensitive ears, put them in right before it starts
