I am new to this so I thank anyone in advance who can help me out. I have questions on several topics. Use will be 40% music/40% TV (mostly football)/20% movies (and perhaps 100% irritating my neighbors--although that is not my intention, so if this factors in to subwoofer advice, please consider).
My setup is as follows:
2 RF-82 ii fronts, RC-62 ii center, Denon AVR-1912, PS3, Panasonic 65GT30, Subwoofer (yet to purchase, need advice)
Room: Odd shaped, living room approx. 20'x20', with 12'x1' open dining attached, fairly open to kitchen, 9' ceilings, but the system is under a 10'x10' cutout vaulting to upstairs about 30' high, and right next to open stair wells going up and down. I can't run rear speaker wires, so I've opted to blow out my budget on really nice front and center speakers to help fill the room.
#1, is my Denon AVR-1912 enough to power my 3 speakers (and if so how much subwoofer can it power)?
Surround System Class 7.1 channel
Response Bandwidth 10 - 100000 Hz
Signal-To-Noise Ratio 100 dB
Input Impedance 47 KOhm
Input Sensitivity 200 mV
Amplifier Output Details 90 Watt - 8 Ohm - 20 - 20000 Hz - THD 0.08 % - 7 channel(s) ( Surround ), 125 Watt - 6 Ohm - THD 0.7 % - 7 channel(s) ( Surround )
#2, how much benefit will I get from bi-amping the RF-82 ii's? And is it difficult and worth the time? Are there any disadvantages, like poteential to blow a speaker?
#3, what type of speaker wire should I get?
#4, Subwoofer. Here's where I might sound stupid. Will I need a subwoofer? If so how much subwoofer to blend right with the speakers? And how much subwoofer will I be able to power with the Denon--or do powered subwoofers not draw from the Denon's power? I've looked at several subwoofers below, but if anyone has a better idea please share. Also, what kind of wire/line will I need for the subwoofer?
I found a great deal on the SW-310 subwoofer for $500 (reg $1050) from Accoustic Sound Design where I bought the RF and RC's from.

Thanks again, as I have no clue what I'm doing. Have I made any serious errors so far?
