Well I plan on taking most of my night shots around 2 minute exposures. So can I still use a low ISO then?
Yeah, that's a long time. You probably can.

Also thanks to all your help I am also learning up on aparture. I guess its a good rule of thumb that when doing night photography its good to use aparture settings between f/4 and f/11. Is this correct?
There are too many factors to say that that rule of thumb is correct. If nothing is moving, it won't make much difference if you adjust shutter speed to compensate. Except that out-of-focus light sources in the picture may appear as circles if the lens is at its widest aperture (lowest-numbered f/stop), but they will look like the shape of your aperture blades at other settings. That might be hexagonal, 12-sided, or almost perfectly circular depending on how your lens is built. If the subject is moving, aperture and shutter speed become independent to some extent. Aperture will govern how wide/bright the tracks of moving lights are, and shutter speed will govern how long they are. Thus if you are shooting a fireworks display, for example, the rule of thumb is to set the aperture where you want it (generally f/8 with ISO 100 is my practice), and leave the shutter open until you get a few nice bursts, no matter how long that is.
The good thing is that with digi you can always check the pictures right away. Trial and error is often required with night shooting.
