1. Destiny requires PS+ for any of the online features (co-op, pvp matches)
2. No
3. Not really
4. It's a large online connect first person shooter. Gameplay wise it is similar (at least from what I can tell from the beta) to Halo gameplay with big floaty-ish jumps and precise shooting. IT IS NOT AN MMO.
You can play however you want. You can do the campaign by yourself, with friends (online/offline), do co-op only, or play vs other players in crucible matches.
During the beta I played a lot of the pvp matches and it was basically a Call of Duty-like domination mode with three different flags.
The only real MMO aspects of the game is the leveling, but it's more RPG aspects rather than an MMO. You upgrade your character's skills (1 of 3 classes you can choose from) and it's actually a pretty in depth system.
