My spoiler-free advice: Don't feel pressured to do everything all at once. The game is designed in a way that you get the "best" results if you rotate between the different aspects like a madman, but it will feel like you're getting nowhere if you try to juggle all that stuff. Plus: Some "best results" would require you to know about future events 'way' in advance.
Just do what you enjoy most the first time around. You can still powergame and take a ton of notes in future runs. ;)
