I honestly don't try to coordinate at all because my soaps/shampoo scents don't really last long enough to interfere with anything. Maybe this is because I shower at night and everything has a nice long time to sublimate off me? The only thing I use during the day other than perfume is relatively unscented lotion (just because I've found that kinds that focus on the scent often aren't very good lotions in general...and often this is the case with soaps and shampoos, too, now that I think about it....)

If I do have something particularly smelly, though, I'd try to coordinate soap with scent (I am notorious for having multiple soaps...soaps was my first smelly addiction. >_>)
