Biznus97,
Disclaimer: I have an oddly shaped room, and I'm still not convinced I've found optimum placement for best tonal balance. Given that...
Both speakers are 20 inches off the rear wall, measured from the back of each speaker. The right speaker is 16 inches off the side wall. The left speaker is four or five feet from the left wall -- that's by necessity, due to the room shape. My listening position is more or less centered between the speakers, about 10 or 11 feet back.
I'll add that a nice thing about the Ohms is that the radiation pattern does provide a wide "sweet sweep," meaning that your listening position is flexible. It's a real plus in rooms like mine, where there's one piece of furniture to sit on (a day bed) that's tucked into a "niche" in the room and can't really be moved.
