1) no idea
2) Persistent world, all victories are temporary. The main objective is to fight a war. They're adding in warpgate taking down the road, but right now all capping a continent does is a small resource cost reduction for infantry/armor/air depending on continent.
3) Take a look into enabling ultra settings (go back a few pages) or turning on PhysX. With Ultra settings/PhysX on I get 45-60FPS and 99% GPU usage. The ultra settings let the game offload more to the graphics cards and improves performance on high end PCs. The game is very CPU heavy simply because of the scale of it.
I will look into the Ultra settings as well, but it seems the game or Nvidia needs to come up with much better drivers.
The scale of the game is amazing and although I am not a fan of F2P games because they are usually not AAA titles, I liked Planetside 2 and want to get more into it.
I really hope to find a nice bunch of people from OCN which plays the game on European servers.
