Nice setup, now you need to centre everything more, you're speakers are off centre from your tv, as Mogorf said spread them out more for better sound, I would also get rid of those candles on top of your woofer, don't they rattle? And last do a little cable organizing with those cables on the floor.
as for the HDMI switching, get a Logitech Harmony one remote. Press one button and changes activities and done.
