That's really two questions.

The answer to question one: It says 'if able' because if it didn't it would read 'when attacking with a primary weapon, the defender must spend 1 focus token.' Which means if the defender did not have a focus token, the attacker could not legally attack with his primary weapon. Likewise, 'when defending, the attacker must spend 1 focus token' means that, so long as you never focus, you could never be attacked. Which would be pretty sweet. By adding 'if able' it makes the loss of focus into an optional aside of triggering the card, rather than a necessity.

The answer to question two: Yes. You can spend a focus token to change zero results. This is important for certain pilot and Upgrade abilities such as Garven Dreis and Keyan Farlander.
