I'm no pro either and have a lowly Canon SD960 point and shoot. If it helps, I've played around with Night Mode, ISO 3200 and the Manual/P settings and the settings I found most true to life were using the long exposure setting at 1 second @ ISO 200. This seemed to be best compromise between capturing enough light and having a noise-free image. A tripod is a must. I'd even recommend using the timer function so the camera is even less disturbed.
