Be aware that taxi's can get very pricey in the city too, and they will probably try to take advantage of tourists. @ _ @ Seriously, subway is the way to go. hopstop.com will help you get from point A to point B with the subway, and it's $2.25 no matter what distance you go, as opposed to a taxi that can easily run you $20-30+ if you aren't careful.

Midtown, anywhere around 35th-50th streets will be expensive. Times Square is 42nd Street, so avoid finding a hotel there, as prices will be more. Look around, look further for hotels, there are some cheap ones if you aren't in midtown.

As stated above, obviously no cameras. This is nothing new for a Jrock concert. Assume no water bottles either, as that is a usual policy. Don't try and bring any in, safe yourself the trouble.

From what I know of the venue, it's general admission, there is a balcony like thing around, which seems pretty nice... I need to go to a concert there BEFORE October to scope out the venue, and if I do, I'll get back to you on that.

I assume lining up early will not be a problem. Keep in mind this is a 3,000+ capacity venue. People will be in line early. I guess only time will tell if VAMPS do something with NYAF.
