Speaker placement is easy, just put then as you would any normal 7-channel system. I’d put the couch about 10-12 ft. back from the screen. I’m no acoustics expert, but it seems to me that your large dimensions would put the speakers some distance from the side walls, which should de-emphasize side reflections more than you’d have with a smaller room. There is some debate and more importantly, research that suggests early reflections are more beneficial than not. Here are a couple of articles you might want to read through:

Good article about room acoustics dispelling myths about comb filtering and early reflections

The worst problems with square rooms tend to be with the low frequencies. They can be dealt with by utilizing two or more subwoofers.
