I have a story for your 2nd request. You really need to read The Radio Wedding 'Verse (http://tinalia.livejournal.com/36352.html) by tinalia. It features Jared and Jensen marrying, their first dance, and the progression of their life together. It's quite adorable :)

Also, do you mean that, for your 4th request, that the boy(s) are being obvious in their pursuit, or oblivious?? If oblivious, keep_waking_up has written an adorable story called Punches and Pastries (http://keep-waking-up.livejournal.com/23222.html) featuring badass omega Jensen and the adoring alpha Jared who woos him :)
