Questions

1.What other components should I get I was thinking I would need a power conditioner to protect my HT Equipment is there any other items that I need to get besides the items that are above?

2.Can Someone give me information about power conditioners I know close to nothing about them?

3 If I buy a Power Conditioner should I buy a battery back up as well?

4.If my family want's to just watch tv without surround sound, just the TV speakers, would I need an optical cable as well right?
