As you are apparently moving to your first SLR, I sincerely think it won't make much of a difference which one you choose (cost aside, of course).
Both are excellent cameras and you will have a great time learning all the nuances that a more capable equipment (compared to a point and shoot) offer.
In my opinion, what you may want to consider are ergonomic factors, not so much picture quality. Since you are moving from a point and shoot, the biggest differences in this respect are going to be the weight and size of the new camera.
Try handling both cameras before you decide, you may find that one of them fits better your hands and this could be the deciding factor. Keep in mind that you may need to carry the camera all day long and there's a lot of difference between carrying a P&S and a SLR.
After you choose one, enjoy a whole new world of photographic possibilities that only a SLR can offer. You will certainly appreciate the super fast focus speed and the capability to give more impact to your subjects using shallower depth of field (DoF) than you current P&S could ever offer.
Considering the lens choice, I'd recommend you going with the kit lens for now. After you have learned how to handle the new camera and noticed any situations where the kit lens weren't enough, then you may want to add a second lens to your setup.
