Crew/compartment performance question?

[MarkShot]

Unlike earlier subsims, SH3 models the crew and performance based individual areas as opposed to a simple: novice/veteran/elite.

When in SH3, when a compartment has a full green bar is that the best peformance you can get or can you still get improved performance by putting crew members with the appropriate qualification badges in the compartment?

Also, is there a detailed list of how each compartments behaviors are impacted by crew performance?

Finally, is there a way to save a crew for future use? Suppose I am personally not into the crew management aspect of the game (I already know how to use SH3 Cmdr to turn off fatigue) ... is there some way when I start a new career to easily begin with an experienced crew without having to hand edit the crew in SH3 Cmdr?

I there a crew record which can be saved copied back into a new career to bring my groomed crew back to life?

Also, if I upgrade ships in SH3, do I start again with a novice crew?

Thanks.
