Every single story about facebook has a post like this, and I'm so tired of reading them.
First of all, why would you even consider competing with Facebook? You do realize that outside of the valley, there are companies not packed to the gills with ruthless nerd geniuses that would be much, much easier to disrupt? Facebook isn't even ossified like Google or Microsoft. They'd just reimplement your killer feature in one of their hackathons.
P2P social network won't work because it's way too hard to do any analysis on the data of the system as a whole. How would you implement a newsfeed? It would be a nightmare.
Regarding having two categories of friends, it's already doable with friends lists. You can do exactly what you are saying with a friends list for acquaintances/grannies/whatever. Or you could just not accept so many friend requests.
