lothario said:korpah, there is a difference between a Minister (which you can assign one of your comps to) and a Steward (which is always a certain NPC attached to a location).
Having a minister with high skills does not do much for you, but a Steward with high skills is awesome to have... which is why you can schedule a training session with them to improve them. Just about every non-combat skill is important for them... but Engineering can be said to be the most important, since it determines how fast they can build stuff. Don't try having them build anything at a location you own until you have trained them up at least once to your current skill levels in your party!
