There two non-anon Monero core team members, five anon.
Is fluffypony non-anon since he appears to be the most prolific dev in terms of the code?
Yes, his full name is on the web site. I'm not sure who is the most prolific, the stats can be misleading in some ways, but I'm sure he's put a lot of time, effort, and money into the project, without question.
If yes, where can I find all his public identity information, videos, photos, address, etc?
I don't know about his address, although he does have businesses whose addresses may be published (again I'm not sure), but his photos, videos, full name, location (at least country, not sure whether more than that), etc. have all definitely been posted. I think maybe pictures of his wife too, but I'm not sure about that. Same with David Latapie (except the wife).
Anonymity or not does seem to correlate with performance.
There are many, many examples of non-anon who have defrauded the community.
I don't know whether it correlates or not, and I doubt you do, but individual cherry picked examples do not demonstrate correlation or lack thereof.
