Josh, what I asked above about aperture ranges is the big thing here. The EF-S 18-55 has a range of 3.5 at the wide end to 5.6 at the zoom end. This will most likely require a tripod with a remote release, as you're gonna be pretty close to 1 second or greater exposures to get anything decent with available light. The best EF-S lens for this that I can find is this one: http://www.bhphotovideo.com/c/product/42..._8_IS.html but it's still gonna require 1/20 or 1/10 second exposures.
The rule is: the longer the shutter is open, the more light the camera can grab. of course, when it comes to camera shake, the shorter the time the shutter is open, the less shake you get. By having relatively small apertures (large openings), you can reduce the amount of time necessary to get the light into the camera.
Experimentation is key. I use two different $2000 lenses to get my available light stuff.
