1.- Yes.
2.- No. What it means is that, if it is a legacy character and it had retainers in v1.x, the retainers where, lets say, "taking a break". Now that you are back, you have to call them back too... aka "rehire". If you already did, then there is nothing to worry about. Make sure you hire both of them even if you remember using only one, just to be on the safe side.

Also if I remember correctly, you gotta take all the stuff out from the calamity savager. He must have something, since they took most of the stuff you had in your inventory from 1.x and gave it to him.
