The linking functionality in co-op has not been implemented yet. The host needs to ask a companion to leave the party, and then the other player can re-hire them (from the King Crab inn, or the Hall of Heroes, if you have access yet).
There is another companion to be found in Cyseal, as well, that your husband could recruit (as long as one of you did not take the Lone Wolf trait). He is not too far from where you found Madora, actually...
Flee used to teleport the entire party away, but now that a distance check has been added for opponents, it may have been changed to individual characters only.
I don't think the hide helmet option not working has anything to do with hair.
The other issues are known.
Using the map to move is on the to-do list. You can already rotate the camera (hold the middle mouse button down and move the mouse); if you meant more:
360° camera rotation - How to.

The bonus points from All Skilled Up and Bigger and Better will show up after the game is started. If they were added during character creation it would be a little messy allowing you to switch talents, since the game would need to take the points back, which could already have been distributed.
