I have my Sunsun spray bar piped across the top left side of the tank (rather than the back), pushing the water left to right, and the input tube all the way in the right corner. Just a personal preference thing, less visible. It might not fit with all the spray bar attachments, not sure how wide your tank is. The extra power head may not be necessary, either. How much substrate did you use? Again, personal preference, I like a deep bed. All that said, the aquascaping is pretty nice.
