1. Any other is just a variation of the above, which are all basically the same. The only 'difference' is the visual representation.
2. Hexadecimal is best as it makes it obvious what each bit represents, and is easy to visualise when flags are used in combination.
3. Only define a zero value if it has any specific meaning.
