I have the 18-55mm kit lens on my DRebel, and it's not a bad lens at all. Sure, when you compare it to a top of the line L series lens, it's not the greatest, but the kit lens still gives you pretty good results. The kit lens is a pretty good all around lens and would work for what you plan on shooting. The only problems I see with it is the max. aperture may be too slow for low light, indoor shots and you are loosing some focal length range over your P&S. The 28-135mm that you're looking at has the same max aperture as the kit lens, but the IS should give you an extra stop or so to help out in low light. From what you have said in your previous posts, I think the 28-135mm IS USM lens meets your needs. If the 28-135mm isn't wide enuf for you, I would go with the kit lens and save up for a longer lens in the future.
