For your #1
I Wanna Hold You High And Steal Your Pain (http://deancastiel.livejournal.com/2368813.html) Cas was pretty sure he hadn’t done anything to warrant Dean’s rage - he hadn’t scratched the paint on his motorcycle or teased his brother or done any of the millions of things that Dean Winchester got pissed about - but this was the school rebel, the troublemaker, the attitude problem with legs, and he was walking up to Cas. So yeah, Cas was freaking.

Learning To Live Half A Life (http://princess-aleera.livejournal.com/121125.html) John drinks. A lot. And it's exhausting for Dean to try and keep the family together, it wears him out to make sure school's okay for Sammy and himself and then clean up after their father when he's finally passed out on the bed or the bathroom floor. Michael is a safe haven. Michael is different. As long as Dean does what Michael tells him to do, he can pretend everything's okay. At least for a little while.

And one of my favourite fics ever:
Waves (http://archiveofourown.org/works/292406/chapters/467759) Dean Winchester is the average guy: football, college, kid brother, nice car, girls and beer; his life is black and white, that is until he meets Castiel Collins: pretentious, slutty, sweater-wearing genius, who won't even take the time to look up at him from his obscure novel while he insults him. And then everything is shades of gray and Dean is drowning.
