1) Those crazy Turks will take anything

Euros or Dollars are your best bet though
2) Yes they do, you can change them as often as you like
3) Can't help you there sorry as I've not been

5) Yes, it's the usual 2 pin Euro type
6) It was last year, I'd guess it is this year too
7) Probably. To the best of my knowledge, the new restrictions don't necessarily apply when flying from many countries
