A lot depends on the recommended listening distance for the speakers chosen. You don't want to sit too much closer to the speakers than the manufacturer recommends though room EQ systems like Audyssey which are available in some receivers and stand alone products can help there. You also don't want to be further from the speakers than the manufacturer recommends, if they give such a recommendation.

The 9' viewing distance for a 50" screen should work well. Don't move too much further away and you may be able to move a little closer, especially with a 1080p screen.

Get some graph paper and draw a room 11' wide on it. Draw the screen where it's going to be (ie on the wall or a little in front of it). Consider where the stand mount speakers are going to be placed in relation to the walls when considering screen location. If you're going for a wall mounted screen, then ensure the standmounts can be placed close to the wall. If you're using a wall mounted centre speaker then you're going to have to go with a wall mounted screen since you want the distances to screen and centre speaker as close to identical as you can get. If you're not using a wall mounted centre, consider how it's going to be supported when you consider how to support the screen close to the centre speaker.

Next mark out the viewing position 9' in front of the screen. Now use a pertractor to mark out lines from the main viewing position to the various speakers using the standard recommended angles. Even if you're not going 7.1, mark out the lines to the rear surrounds and mark points on those lines at the recommended minimum and maximum listening distances for those speakers, or for speakers matching your side surrounds if you're only going 5.1. You'll want to position the rear wall somewhere between those 2 points and you can make your choice on what gives a reasonable length proportional to the 11' width in order to help with room acoustics and avoiding standing waves at frequencies related to those already occurring for room width and height.

At least that's the way I'd go about working out what size room to end up with.
