Is there any death penalty, ressurection sickness, etc?
Yes, if you are killed in combat your total HP and SP will be decreased by 15%, if you die again it will be decreased by another 15%. The Maximum death panalty you can get is 60%. You can work off your death panalty by killing monster, ever colored monster (boss) your party kills will take 2% off your death penalty and your death penalty will also be decreased for 1% for every few monsters you kill. If you return to a mission lobby, town, or outpost your death penalty will be removed completley.
