I think the answer is a two part one because it was a two part question.
'Internal' power is totally different to 'external' power. External power is dependent on muscle strength, mass, speed, timing and the ability to accelerate that mass. Internal power is assisted by mass and is very dependent on timing.
Perhaps the things in common are maintaining structure, using the mind and timing and even then use of the mind and timing are different.
As to the 5 top ways to create power.
External
1. Use your mass effectively.
2. Keep relaxed to maximise speed.
3. Ensure correct timing.
4. Maintain your structure.
5. Focus the mind.
Internal
(Using Tohei's four principles)
5. Use broken timing

Internal
(Using Tohei's four principles)
- Keep One Point (maintain centre)
- Relax Completely
- Keep weight underside
- Extend Ki (extend the mind)
5. Use broken timing
