This is a Wincestial trilogy but very good and fits your #4, #6, and kind of #5: like a slow fire burn (http://users.livejournal.com/_mournthewicked/363415.html)

I'm sure you've probably read it but some great slutty!bottom!Dean in the Phthonus series (http://archiveofourown.org/series/6437).

And for your #3: Bearing the Brunt (http://archiveofourown.org/works/464364#main)

Hopefully some of these are new to you!
