Yes, PSRAM pins are usable as indicated on the rear of the PJRC product card.. They are probed on startup to see if PSRAM or FLASH chips are installed, not sure what effect that may have.

Yes. Those pins can also be used for and other features mentioned on the pinout diagram.
Here's a conversation where I tested them (with photos) as SPI to access another SD card.
As you can see in those photos, actually soldering wires to those pads is a challenge, though it can work.
