I use a 10 speed Campy road crank with an 8 speed system. Some say that you are supposed to put some thin spacers in between some of the chainrings and crank because the chainrings are thinner. I added the spacers, but I am not sure if that is absolutely necessary.
Thinner chainrings probably wear a little faster.
