Super zooms as mentioned in earlier posts are very convenient, but only you know what type of photographer you are and what you like to shoot. And those parameters will change often and very quickly once you start shooting. If image quality (IQ) is important to you, the super zoom will eventually be sold and high IQ zooms like the 17-50 or the 15-85 or the 24-70, will be your next purchases. And then you will start buying fast primes for ultimate IQ. That is the path taken by a lot of the members of this site.
Canon 17-50 IS and a 70-300L would give you greater convenience and superior usability and a super IQ package on a crop body camera.
Good luck with your decisions.
