Though, the 4K7 is not needed, it does no harm. Even if the xstr had the minimal hfe of 25, there would be less than a 1V drop across that resistor.
I have a IN-13 running right now, on my nixie thermometer. The drawing of the pinout, is correct, from the viewed side of the tube. The aux cathode, specifies cathode, so it should be wired as shown.
