Wish I had motives like that to shoot right now. :) I saw this too late to make any recommendations, but I think you made a good choice. I'm using the same 28-135mm on my 400D and I like it a lot. As for macro lenses: One suggestion that I think hasn't been made yet is the Tokina ATX AF 100/2.8 I don't have it, but reviews I've read convinced me that it might make a very good addition to my collection at a reasonable price.
