I think the other poster has spoken to #2 pretty well, but as for #1, I've had a USB OBDII dongle plugged into my car continuously for the last two years without issue. I imagine the wifi chip causes yours to draw a bit more power than mine, though I previously had a Bluetooth module plugged in and it didn't present any issue either. I think it's likely fine.
