One of the nice things about setting up your room - its all free except for the labor. Personally, I would start with a set up with your speakers close to the side walls and toed in extremely so they cross in front of you, well in front of you. I would have the listening position about 9.5 feet back from the plane of the speakers (by the way, I assume you have the speakers out several feet from the back wall?). The axis of the speakers would point about 27 degrees past the listening position. Yeh, I know, the speakers look cross eyed that way, but trust me - it can work! I would also get a test disc with tones (see the Rives site) and a Radio Shack sould level meter which will help you select the best location for bass reproduction for both your speakers and listening position. In fact on the Rives site he has a program and you can just plug in your speakers and the room's dimensions and it will give you a suggested starting location. Have fun, this is IMHOP the most fun and frustrating part of audio. And inches (!!!) make a difference.
