Ctb - typically the zobels are required for solid state amps, but considering their price (evidently they are not free anymore - $20), why not play it safe and get them anyway. I think they are sold in pairs so you need 2. Get the jumpers while you're at it.
As for damage, you didn't mention the animal factor. Yes a puppy can chew through them if they work at it long enough. If you can run them under carpet that would certainly help.
