Welcome.
What kind of night shots are you going for? Some require tripods (streaking tail lights of cars, some night architecture), but others, like street photography merely requires raising the ISO up around ISO 1600 and holding the camera real steady.
The T3i has pretty good high-ISO performance, but starts adding a lot of noise past ISO 1600. If you need to push for higher ISO, then you'll need to start shooting in Raw and invest in some noise reduction software. Canon's Digital Photo Professional came with your camera and is a great way to start playing in the Raw world without any incremental investment.
While you're learning exposure and getting used to your camera by shooting a lot, JPEG shooting is an okay way to start. Ultimately, you'll need to go to Raw, if you want to get the most out of your images.
