You would need all of that to build this circuit in the proto area..... since you are reusing the IGBT circuit (which would normally be used for ignition if you were tfi.) most of this circuit is already built....
the 100ohm is between j11 and ignin... The IRLZ isn't used because the IGTB has a TIP120 already. there is already a 10k resistor in place at R43..... and you will be using the diode....
you only had the placement of the 10k resistor wrong..... if you want you can place it tapped into the IGNIN pin over to the R43.. this will help with flyback
