Use the calculators supplied by the site to figure out impedence. Treat each voice coil as its own speaker on the calculator. Add rms power requirements for speakers together to get total power handling.

yeah parallel/parallel to 2ohm

you could use a 2ch amp if you wanted, but unless it was 2ohm stable bridged (1ohm stereo stable) you would be wasting half of the power. And if you did find one that was 2ohm stable bridged, it would be a LOT more expensive than a 2ohm stable mono amp of equivalent power.

Definitely parallel the drivers. VC's aren't as bad to run in series, but when you run drivers in series they create a lot more back-EMF which actually fights the current flow coming from the amp. The mass of the cone reverberating turns the voice coil into a small generator which moves electricity against the incoming power. Not something desirable.
