Been a long time since I've flown the 737. But on the 777 when you loose GPS you start getting ADS-B out EICAS msgs as it doesn't work without GPS.
GPS is normally working 100% fine both in Iraq and Iran, (apart from the small area on departure from IKA) the black spot is normally on the IRAQI/TURKISH border near Syria
As for your other question, yes you get radar vectors normally direct to a waypoint.
