From what I've read of others who know more than I, balanced cables will offer no real advantage with that short of length. RCAs should be fine.
As for what type/brand, there is so much here already that a quick search will lead you in the right direction.
My experience is that you don't have to spend a fortune to get great cables.
Good luck!
PS: I'm a bit jealous of your gear.
