If you can afford a little more...
17-40 f/4L
70-200 f/4L
50 f/1.8
430EX
I used almost this exact outfit for a while except that I had a 420EX flash and my 50mm f/1.8 was the older (and better) Mark-I.
It was a fair outfit but I really missed the range between 40 and 70mm. The 50mm didn't quite fill that range since using it meant a lens switch.
I bought a second camera which helped a little bit but, I was still not happy with the general outfit. Of course this is just my opinion and should not be construed to be applicable to all photographers:
The 17-40L; although a very nice lens just isn't long enough for me to use as a go-to mid range zoom. The f/4 aperture also limits my use as the go-to lens because it is a bit too slow.
The 70-200mm f/4L (non-IS) is a great lens but, for me, it is not a carry everywhere and use in most situations lens. I reserved the 70-200mm f/4L as a lens to either use in bright conditions or to use on a tripod or monopod.
I have gone through several lens and camera combinations until I settled on what is the best (but, most expensive) for my uses: 17-55mm f/2.8 IS and 70-200mm f/4L IS on 30D and 40D cameras.
I carry this duo everywhere and it serves me very well indeed. I no longer need to carry the 50mm f/1.8 lens because of the low light capability of the 17-55mm and I use the 70-200mm f/4L IS 3-4x more often than I was ever able to use the non-IS version.
I will agree that this outfit is probably a lot more expensive than most photographers can or want to spend.
I would suggest the 17-50mm Tamron f/2.8 and the 70-300mm f/4-5.6 IS lenses as a great pair. Although the 17-50mm doesn't have the range of the 17-85 IS lens; it does have a bit better image quality. Additionally, I have never missed the gap between my 17-55m and 70-200mm lenses.
