Inheritance and Statement

I'm trying to learn a bit about how to protect my progress if I'm killed at the game.
After reading forum posts and http://salemwiki.info/index.php/Inheritance, there are some things I don't understand yet.
1) If I get "Plan State" or buy a "Last Statement & Will", once I dead, my new character will only get 30% of my progress? There is no way to get back 100% of the humors/proeficiens?
2) The only difference between "Plan State" and "Last Statement & Will" is that with "Last Statement & Will" I don't have to buy a "Plan State" every few days?
3) Any advice on how to do to protect main character as much as possible from getting killed?
