Cable ties are your friend I'm fortunate that I have a server cupboard that I can hide everything in, so it doesn't have to be super-neat.
I have cables coming from the faceplates, but they have units in front of them (TV unit, or a dresser in the bedroom etc) so you can't see that either. Oh, and definitely colour code your cables, makes life a hell of a lot easier!
Let me get some pics and upload them for you, two secs.
