Regarding spark voltage, that's not exactly right. The voltage required to jump the gap depends on the pressure in the combustion chamber at that time: more pressure requires more voltage. That's why an engine with a weak spark system can run OK at low speeds and start missing at high RPM or under load. So for example, although 3kv might be sufficient to spark a plug at idle, 40kv or more might be required for a spark to jump a gap at full throttle & high RPM.
