HW-H750 & PT-AE8000U PJ Question

Hello,

I just purchased a Panasonic PT-AE8000U Projector and found a Samsung HW-H750 sound bar for $200 used I may purchase.

MY goal is to run one long 25ft HDMI cord from the back of the room to the front & connect a few inputs (Cable, PS3 & Xbox) seamlessly connected to sound.

SO, my question is, can I connect my PJ directly to the sound bar at the front of the room (25 ft HDMI) & then run an HDMI auto switch in-between the soundbar to the inputs in (Cable, PS3 & Xbox) so that only the one in use will be audible? is there a better way?

Also I would probably be adding wireless Samsung speakers down the road if anyone sees an issue with this.

Thanks in advance for your help
