Firing order in my manual is 1-4-2-6-3-5
As for the 2 green wires, if you look at the colour of the wires coming from the points you should be able to work out which is which. By the wiring diagram, you have blue, yellow and red wires from the points. If you look at the cylinder number stamped on the points mounting plate you can work out which coil they go to. Coils share cylinders, ie - 1/6, 4/3 and 2/5.
