The bulk of your actual healing done (besides EoL from mastery) will usually come from HW:Sanctify and HW:Serenity, so tracking those and casting on CD (whenever they won't overheal tons or are needed for specific incoming mechanics) is generally a good idea. For dungeons you might want to track Light of T'uure CD since it's a huge healing increase on a single target.
It might also be useful to track things such as Divinity (6s 15% healing increase after healing with a Holy Word) and Power of the Naaru (24% healing increase on PoH after casting HW:Sanctify to know when you should cast PoH.
