I agree with what Ed stated. Since your camera has a max ISO setting of 1600 and your lenses don't have a particularly fast apertures, you will need to use a tripod to get a higher percentage of properly exposed and reasonably sharp photos at night.
I'm fortunate that I can shoot at ISO 6400 and have a couple of f/2.8 lenses. Even with this gear I still get a lot of crappy shots - especially if I am shooting a slow shutter speed at f/2.8. Ideally I like to find an ISO setting and shutter speed that allows me to shoot at f/8 to maintain sharpness.
I also use cameras with full-frame sensors compared to your camera's crop sensor. Full-frame cameras generally produce images with lower noise in low light situations due to the larger pixels associated with the sensor.
Like Ed stated, just keep experimenting (and hope that the scene lights on the rigs are set-up). Your gear is capable of delivering some great photos.
