A couple RaR questions

Hi all,

I just started playing with the RaR mod and have a couple questions.

How do you deal with slaves, native slaves and criminals? Anytime I try to use them they just run away in a few turns. Is there something I can do to set them free or train them or just stop them from leaving?

I really want to buy the nobles, but it seems like the king offers them just after I spent my money. In RaR can I keep cash on hand and not have the king ask for a huge cut? In previous mods (TAC) and the original game I had to spend all my money as it came in. Is RaR more forgiving?

How can I increase the odds of my king telling me to go to war? It is a huge boon to me when he gives me a ship and artillary and when asking me to stop the war gives me a noble...I want that to happen as much as possible during a game!

Thanks,
Windfoot
