Need help in making decisions - new to the game

[ManOWar2]

I'm unsure wich talents to give to Aloth and Durance.

 

Also, is it better to jail Nyrid or kill him ?

 

My instinct was to kill him, but also because I do not have any jail built.

 

Also, is it better to complete the Raedric missions before completing chapter 1 ? I ventured into defiance bay before doin that Raedric quest.

 

Thanks for the help.
