My friend and I (especially will autumn coming up) are interesting in shooting our own take of the "ghost hunters" craze. I would also like shoot haunted houses and corn mazes and what not without carrying a light and ruining anything. Could buying something like the PhantomLight infared or Sima infared light as well as an infared filter work? or do I have to invest in a camera?
T3i Nightvision?

you have it kinda wrong. Throwing an IR filter on your camera at night will not make it night vision. It will block out all of the light that falls outside of the IR spectrum. You would do better to buy a cheapo IR flashlight http://www.dealextreme.com/p/dx-12-led-ir-infrared-flashlight-silver-3-aaa-2047?item=6 and testing that out with the camera sans filter.
The other option is to remove the internal IR filter that is already on top of the sensor http://ghonis2.ho8.com/rebelmod450d1.html
this MIGHT give you a chance. but take care because you are taking apart the camera and touching the sensor

Putting an R72 filter on your camera will let lots of near-IR, and not a lot of visible light into your camera. However, the sensor's sensitivity to near-IR is very low, so what you usually end up with are some extremely long exposure times. Even with a very fast lens (f/1.4 territory), your exposure times in daylight will be in several seconds, rendering it totally useless for video purposes - Unless of course, you remove the IR filter from the sensor and have your camera permanently fixed as an IR camera, but from what I understand, even still the sensor's IR sensitivity might be too low for getting shutter speeds around 1/50th in anything but the brightest daylight.
I'm just looking back at some old photographs I shot in daylight with a Nikon D70s and R72 filter. I was getting 30seconds at f/11 at ISO 200 in cloudy daylight. To try and get that shutter speed down...
30s f/11 ISO200
15s f/8 ISO200
8s f/5.6 ISO200
4s f/4 ISO200
2s f/2.8 ISO200
1s f/2 ISO200
1/2 f/1.4 ISO200
1/4 f/1.4 ISO400
1/8 f/1.4 ISO800
1/15 f/1.4 ISO1600
1/30 f/1.4 ISO3200
1/60 f/1.4 ISO6400
So given similar exposure conditions, just to shoot in daylight, you'd be looking at f/1.4 at ISO6400. I really can't imagine any IR flashlight being able to rival the sun in terms of illumination. You could always push the ISO harder if your camera is capable of it, but given that you mentioned a t3i, I think this only goes to 6400. I'd normally call that a bit high, but you can kinda get away with it to some extent with a deliberate "night vision" look.
