Regarding Lockpicking: no not realy. If you are in a town and try to brute force a door, this should be dealed the same way like thiefs are dealed. But if i'am in the wild, it simple booring to hit the same door for several minutes.
There should be some doors (iron, magical ...) who are uncrackable by brute force but openable by lockpicking.
I know that Jahan is capable of the healing spell but after the start it's not offordable to the player, cause you don't have the money. you have to farm some gold
