1st question... is it even possible to run ppsspp full speed on android??
Yes, for most games not all.
2nd question... if yes, what sort of hardware would I need?
None that you have listed. You'll need to use moderate frame skipping on those devices with some speed hacks enabled. The only hardware on Android that will run most PSP games full speed with no frame skipping are the Shield TV/Tablet devices. But they aren't phones.
