The 200mm is going to be way too long to use.

I use the 50mm f1.8  when I shoot concerts. I try to keep shooting around 1/50th - 1/120th of a second, with a 400 - 800 ISO, around f2.8.

Its also a good thing to hang out with the band a little before the show, so you know who they are and have a general feeling of what to expect.

The most important thing is to have fun. Sing with the music if you know it, and just rock out. It helps with calming your nerves.

What kind of concerts are you going to be shooting?
