I agree with going with more expensive lenses from the start as long as the photographer knows (a) what they want to shoot, and (b) how to shoot it. That was the case with me... When I got my Rebel T1i I already had some experience with photography from playing with my PowerShot G9 for a couple years, and I knew exactly what I wanted to shoot (reptiles, amphibians, insects, and birds just for identification purposes). So when I was in the market for a new camera, I just got the body and skipped the kit lens because I knew right off the bat it wasn't going to be adequate for what I was doing. I invested in higher-quality lenses right from the get-go, and I'm happy I did that.
But for someone like the OP who is completely new to photography and likely doesn't know what type of photography he is going to concentrate on (if any), going with the more versatile kit lens (vs. an assortment of prime lenses) might be a good idea while he's learning the basics.
