Yes, Ferro would be *that* Ferro. You would probably rather have him around and there is no way to resurrect dead NPCs/RPCs outside your party.To prevent further injury, don't get in any fights around him, unless you can get to him and heal/protect him.
As for the Templar guards, talk to the other one. He should tell you to go in and talk to Al-Adryian (who is who will send you).
