I'f you're talking about Xbox Live, yes, you need gold to play any game online.
You need the PS3 so you do not have to have live gold or a charge for online gaming. For the same subscription cost as Live Gold Playstation will give you free games with the Playstation Plus
Of course you need a membership. That is how the company earns the money to make the game. Computer graphics are not cheap.
yes, call of duty world at war has online. you go into multiplayer and click play online.

Yes it can.
In order: Call of Duty: Finest Hour Call of Duty 2: Big Red One Call of Duty 3 Call of Duty: World At War: Final Fronts All of them have online except for "Call of Duty: World At War: Final Fronts" I hope this helped :)

No there is no Online or Zombie as it is a unique game for only PS2 and not like the PS3 Call of Duty World at War
