I can answer the first bit!
EX does indeed have folding mirrors (at least, mine does, and I don't recall adding them as an option...)
It does work from a switch - on the drivers door, near the electric window buttons.
Getting to work from a timer (or indeed whatever!) would be good - it's a PITA cos currently (no pun intended!) you need to have the ignition turned on...
Welcome aboard by the way
