You will only have trouble if you shoot at maximum or minimum f-stop (lens openings). If you have the choice of buying it WITHOUT the lens and can afford to get the 17~85 instead you'll be most likely happy for many a day... but again the 'stock' lens, though very crappy built, still will handle most situations just fine.
This man speaks the truth.
However, you can take very fine pictures with the kit lens -- the art is created by the photographer, not the equipment.
However, as Reinman states, the kit lens does have a noticable sweet spot in clarity and contrast in the middle f-stop range, so if you're going for most resolution possible, use those f numbers.
However, don't let that keep you from experimenting with the lowest and highest stops on the lens. It's a great learning experience to
experiment. While you're saving money for your "L" lens, experiment with all aspects of the lens that comes with your camera -- large and small aperatures and how they affect your image and other aspects of your camera (like shutter speed). I mean, what do you have to lose? It's not like you're wasting film!
Congratulations on your purchase, and be sure to post pics! I bet there are some pretty knowledgable photographers on here that can help if you have problems.
Also, bear in mind that while the "L" lenses are overall much higher in quality -- both physically and optically, they *still* have sweetspots in f-number just like your kit lens (even though the "L" lenses, wide open, are probably as clear as the kit lens at its best aperature.)
Good luck!
