50,55,and 60mm macro lenses are really not all that useful for many things--they force you to be really,really close to things in order to get large magnification--as close as three inches from the front of the lens. Longer macro lenses in the 90, 100, and 105mm lengths are really much more versatile.
My other choices would be the 18-135, the 55-250, and the 85mm 1.8. The 28-135 is a poor choice for a 1.6x sensor--Canon seems to be trying to fob those off on USA buyers, but not in Japan or Europe.
Although it is not a top-quality lens, if you can only buy *one* lens to get started, I guess it would have to be the 18-135.
