They're all good questions. Wire lengths aren't a problem in terms of time, and given that the surrounds are not full range (ie they don't do deep bass) it's unlikely that anyone could make a good argument from an impedence POV either.

A bigger issue is the fact that the surround speakers are a different distance (probably closer) from your ears than the mains so speed of *sound* makes a difference, but you can adjust for that in your AVR.

I don't know if any specific type of insulation is tastier to rodents, but the mice around here eat fiberglass insulation so I just try to make sure there is something tastier for them attached to a trap. There's a perfectly good woodpile outside if they want a sheltered place to spend the winter, no need to come inside and poop all over my house.
