So the 24-70 will be suitable if you can get fairly close. If you're renting and know you CAN get close, I'd recommend the 17-55 2.8 IS, the last two letters being key. IF it is especially dark in there, as it probably will be, the IS plus the fastness will allow you to remain mobile and get a variety of shots as opposed to hunkering down with a mono/tripod and getting the same perspective all night or having noisier shots from higher ISO.
I'd start at ISO 800 and wide open, and if you're getting fast enough shutter speeds you can stop it down a bit to make sure (slightly) missed focus doesn't ruin a shot. I wouldn't recommend 1600 but you can if you must... Also make sure you set it to look only on the central focus point, lock focus (button or switching it off on the lens) and take a few shots from that perspective to make sure you don't miss something die to focus hunting.
Have fun and experiment, it'll show well in the shots!
