Q60: If I make an attack that doesn't do damage and roll a crit, do I add the bonus damage from feats/enhancement?
Example: I have a +1 holy symbol and roll a critical hit with Command power, which deals no damage. Should I add +1d6?

No, powers that don't deal damage don't deal damage on a critical hit from implements or weapons.
