Would I be able to go really early to stay in line? I want to be close to the stage so I will want to go early, like hours early. Would that be a problem?

I don't think there is any problem. If you have a seat you don't need to go early but if you are standing and you like the artist, then you should go early. Check what time they open for the general availability tho. Have fun!

There are so many restaurants around it wouldn't be any issue

I had a signed sitting never been there when it's first come first served.
