i just built a 55cm, i would be too small. i'm just shy of 6'2" and the standover is just perfect. i do wish the top tube was a bit longer so i could go with a stem shorter than 110mm.
so your frame may be just a hair big, but you'll get used to it. not such a big deal on a road bike.
as far as the bars go that all depends on your stance preference. do you ride in drops or find your self up top most often? i went with a standard nitto road bar for now, but may pick up a set of bullhorns for more relaxed riding.
