Karthik,
While you do need a filter (I have used a Hoya R72) you will also need the right lens. So far I have not found it yet. With some lenses, like the kit lens that comes with the 350D, you get a bright "Hot Spot" in the middle, with other lens, the images were very soft.
Some people, who upgraded to a new camera will have the old camera adapted to shooting only IR by have the mechanism built into most if not all digital cameras that filters out IR removed.
Provided you can get all of this to work, you will probably need a tripod as the exposures can be as high as several seconds. You will also need cooperation from Mother Nature. You will need a very calm but bright and sunny day. Having a few clouds in the sky will help as well.
Hope this helps.
