Although Quinn will use Harrier's attack animation against inhibitors if it was her last attack prior to that, the bonus damage will not apply.
Spell shields will not block the mark or the applying autoattack.
Harrier's targeting priority is as follows:
Last unit hit. If the last unit hit was a small minion, it appears to select a different target.
Lowest health enemy champion.
Lowest health enemy minion.
Harrier's bonus damage will only apply for basic attacks that are declared after the mark is applied. The mark will not be triggered for basic attacks that were en-route when it was applied.
Attacking a Vulnerable target will place Harrier's passive application on a one second cooldown instead of its full duration if the mark was originally applied by Blinding Assault or Vault.

Active:Quinn commands Valor to fly forwards in a line, stopping when he collides with a unit and dealing physical damage and applying nearsight for 1.5 seconds. Non-champion targets are disarmed instead for the same duration.
Active:Quinndashes to the target unit, knocking them back a short distance, dealing them physical damage and slowing them by 50%, which decays over 1.5 seconds, before leaping back and landing away from them.
Quinn and Valor are effectively considered to be the same unit by the game - as a result, they will share the same champion statistics, cooldowns on their basic abilities (unlike many other shapeshifter-type spells) and will both die when their health is depleted.
