If you go on all programmes/accessories there's a thing called 'snipping tool'. You can also take a screenshot with that and save it. (you'd have to leave Kerbal up though while you get it up so it won't really be able to do launches)

Back on the crew thing There's an astronaut complex in the works apparently so you can train up your astronauts and have different types (engineers, pilots etc.). You'll probably be able to mod in some when that gets released (but it might be a while!) Its all on this page (along with a lot of cool other features): http://kerbalspaceprogram.com/wiki/index.php?title=Planned_features
