G7 & Rock Concert Photo Assistance

Hi All

I am going to a rock concert this Saturday. I have to double check the day of, maybe I'll get an answer the day before if camera's are allowed. My G7 and I assume I can not bring the 430 EX.

So, this is a first. What settings other than the obvoius, Auto exposure, Auto ISO should I use?

Do I change exposure compensation?

Do I change flash compensation (assuming I am using the built in flash)

I am thinking I should use face detection (have that selected)

Please advise for this once in a lifetime chance

Appreciate it!
