What kind of elements are these?
471KD07

This is a variable resistor but not like potentiometer. In potentiometer , resistance variation is linear . But for varistor , it's resistivity changes is non linear, it mainly works like diode , specially zener diode and mainly use to protect the device. It has a threshold voltage below which, varistor's resistance remain so high as it is non conducting. When voltage crossed the threshold voltage, it became conducting. For your better understanding , you can go to wiki . 

So what you are looking here is not resistance value but voltage and you may need to replace varistor with zener diode in EveryCircuit app as it do not have varistor (as far as I know).For this varistor maximum allowable voltage is 470V

CY400 474JE

this is CY400 model capacitor with value 470nF. 
This link will teach you how to read capacitor code information .and JE most probably manufacturer's name. Some write it at the end of the code or model name.
