question 1 is, I am going to be running one Polk Audio SR subwoofer, should I get a 2 channel amp or a mono channel for just one subwoofer?
That all depends on the voice coil of the sub and what resistance the amp is at.

For instance, (this is a mistake i made) I have a dual voice coil 4 ohm sub, and a 400x2 amp at 2 ohms. So I can only wire it at 8 ohms unless I get another sub.

I would get a 12.
