Yes. I think the 175 would be a good choice for a room your size. With movies it adds a lot of extra sound that I wouldn't have without it.

As to the surrounds, I can't testify because I've chosen to go without them at this time. If I could pick up some on the auction that might be another matter for later. But I don't miss what I don't have.
