A lot of people are suggesting the 17-55, and it's a great lens. I went the 24-105L route and I'm not disappointed. It can be had for $200 cheaper than the 17-55, is weather sealed and has a slightly better build quality. I find it's still useable indoors despite the f4, thanks to the IS. The biggest knock on the 24-105 is the barrel distortion, but you don't really see any of that on a crop body. Some also say that the 39mm effective focal length isn't wide enough for landscapes, but I have the 10-22mm for that (which is also a must have for 7D owners), so the 24-105 compliments it well. The 70-300L would be the only other missing piece you would need to complete the trifecta and have the 10-300mm focal range covered. And for $350, add the 50mm 1.4 for indoor use and for portraits.
