The "CPU 0" temperature under AMD processor section comes straight from the CPU package sensor. Unfortunately later AMD CPUs seem to have this sensor extremely inaccurate, especially at lower temperatures. They should provide more precise values when the temperature gets closer to the critical point.
The "CPU" temperature under IT8712F comes most probably from a sensor (diode) placed near the CPU socket, however only the board designer (ASUS) knows this exactly.
So it's hard to make a precise judgment, my personal opinion is that the "CPU" value should be more precise (I don't trust the internal AMD CPU sensors in later CPUs at all). You might want to verify this with an ASUS monitoring tool.

I'd say ignore the CPU temp as well, but I know how unreliable the internal core/package temperature in later AMD CPUs is.. And AMD has acknowledged this issue, but there's no fix for it...

ATI PM2 is a tough sensor, in many cases not used or calibrated. I think this is such case too, so best is to ignore it.

Yes, it's a bug in HWiNFO that will be fixed in the next build.

The problem of AMD internal CPU temperatures cannot be fixed in software, it's a hardware flaw. Some tools seem to add an offset to the the values read, but I believe this is not correct.
You might rely on an external CPU sensor placed close to the socket, but this is mainboard-dependent. Though that won't provide the internal CPU temperatures.
