2. What about if the SP120 is used on a push, and the AF120 for exhaust, not pull? assuming the case would be on a twin tower heatsink, or a single tower?
1.) I wouldn't, innevitibely the SP120 would burn out the AF120. I'm not saying it will happen right away.
2.) This would be just fine as there is a zone where the pressure can be dumped and isn't being forced directly into the AF120 from the SP120 so you'll have your rear-exhaust still pulling out a lot of that hot air but not having it forced directly in.

Fans with very close specs to one another (in airflow & pressure curve) will generally be fine.
While some folks may encourage the mixing of fans, I come from more of an industrial background on this topic so I don't support the idea as one can over power the other.
