1) If you are plugging this to a bus that is already terminated at both ends, your device in the middle must not have termination, and it must be removed.

2) The 4.7nF capacitor between 2 resistors is not mandatory. When the 120 ohm resistor is split into two 60 ohm resistors with capacitor in the middle, it is called split termination. The capacitor is there for terminating the common mode signal voltages that would otherwise be unterminated. And since most likely you are connecting to a bus that is already terminated at both ends, you must remove the resistors and this capacitor as well.

3) There is a 47pF on both CANH and CANL wires, not just on one of them. It can be there for many reasons, such as limiting slew rate, filtering of noise spikes or just for filtering radiation or reception of electromagnetic interference.
