I'd say you've got a darn good plan already. Personally, I'd go with Blue Jeans because of a few reasons:
- Their money-back guarantee
- Completely customizable length, so you get only what you need
- Utmost assurance of a quality product
And yeah, Sound King should do you right as well. As long as you go 10ga or 12ga (12 should really be sufficient), you'll be fine.
You're definitely right, the majority of your money should be spent on speakers, quality electronics, and room treament, not cables.
Also, I don't know where you plan on getting your optical cable from, but you may also want to compare prices from
Impact Acoustics and
Ram Electronics are both great places to look.
As far as power protection, make sure that the power rating is sufficient. If you're running 900watts of RMS power, then you should go for a 1.5kVA protector. The 1000 would probably suffice, since you'll most likely never draw 900 watts, but having headroom is good so you aren't running your power protection at near capcity. I know monster makes quality stuff, but you might also look into Panamax stuff as well as a favorite around here, the TrippLite Isobar.
