You're also going to want to reacquaint yourself with fighting, specifically the stamina system. I recommend fighting monkeys, they are formidable sparring partners that typically show a degree of mercy after whooping yer butt. But, I wouldn't recommend going Assistant until after you get the hang of wrestling the controls.

Roboticist is a good role, you get to learn a lot about surgery and revive the dead! Mining is great for learning how space works and avoiding human contact.
