If you're on a budget, personally, I really like the 18-55mm kit lens. As a filmmaker, a wide lens is essential.
<3Leo is correct -- it's not a particularly good lens. However, I still recommend it as a starter because it's versitile, and you get that all-important wide lens. A good prime wide lens is going to cost considerably more money.
I'm not so sure the 55-250 is such a great idea. I can't imagine very many situations in which you'd want to use a 250mm lens. Maybe if you are making a spy movie, and you need to show the perspective of somebody looking through binoculars, you would want something telefoto, but for "normal", everyday shooting, you'll never approach using that focal length.
The prime lens that most people recommend (and I agree with) to be your 1st or 2nd (depending on if you get the kit lens) purchase is the Canon 50mm prime lens. It's only $100, but it's a decent lens. You might wonder why you would want a 50mm lens, when the kit lens extends to 55mm, and the answer is that it has a much lower f-stop. A lower f-stop is going to allow you to shoot in lower light, and/or acheive a much more shallow depth of field, which are two of the main reasons people are purchasing DSLRs in the first place.
PS -- Don't forget about the Kiss X4. The Japanese version of the camera is the exact same camera, but with an instructional manual in Japanese (you can download the English PDF for free). I got the Kiss X4, with kit lens, for $100 less than the T2i would've cost me.
