Action Duration Reminder is nice and easy to show the used skilsl on the other weapon bar + their cooldown/time left so you can optimize your rotation.

Assist rapid riding helps with your mount in order to speed up levelling
Later on you will have sets which can be used to proc for the tank, like "Alcosh", and there are also addons which show you the info about this then.
