Checking if Wifi P2P is supported:

• In code: If you cannot get the system service, it's not supported

  mManager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
  

• Without code: Check whether the option is in the Settings app (Under Wifi)

As per your second question: yes, devices connected via wifi direct communicate without any existing wifi network.
