1. I may be confused about this... but what is "optical HDMI"?
2. The 4308 has 2 HMDI outputs, so you can run HDMI to Zone 2.
3. You will only need one run if you have a Zone 3. Bluejeancables.com sells the components in a bundle if you need a bundle. It has a good durable jacket.
4. I don't know.
5. I believe it's CL rated that you want (flexible and easy to work with)... you can buy it in big rolls and save. Depending on the distance I would use 12 - 16 gauge.
6. Use Cat6 and run as many as you possibly can. All kinds of things are beginning to be networked and you just never know. Just do it!
7. I would use HDMI where possible and Coaxial Digital otherwise.
8. I don't think so, but I'm not totally sure. Somebody probably is though.
9. Another dunno... ???
6. I can't count...
