Fow Armor

Iam thinking of getting FoW armor on a paragon but I would just like to know some stuff first.

Are nightfall characters auto ascended or is their some quest chain or mission to complete?

What materials are needed (other than the ectos and shards) havent been able to find any info on this. Does anyone know? or have a screenie?

and Can Insignias be used on FoW armor?

I think they mentioned somewhere that Existing High End armour would get updated so insignias could be used on them.

I could be wrong.

But i think Anet(or Gaile Gray if you prefer) mentioned this.
