It should answer most of your questions. If you have any specific questions I'd be glad to help.

Primarily through Divine Aegis generation. Your prime DA generators are your level 90 talents (and selecting the appropriate one for the fight is key), followed by Atonement. Atonement is powerful, but the bulk of large DA generation that covers a substantial part of your raid will be from your level 90 talents, whereas atonement will fit the smart-healing niche, providing substantial healing and absorbs as needed.
Healers don't really have rotations. Anyone who says otherwise isn't maximizing their potential. That being said, healing in general, and disc especially, rely on a list of priorities. Disc looks something like this:
Emergency Healing (Will someone die right now if I don't: Pain Sup, Void Shift, Direct heal penance*, PW:S --> Glyphed BH, FH
CD's You're assigned to do at the times they come up (Barrier namely, SS)
Archangel (iff t16 2pc) + Divine Star if talented [Divine Star 2x within Archangel]
PW:S under lucidity (2-3 casts ideally)
Penance Offensively
HF/PW:Solace on low health targets (for ToF) > Regular HF/PW:Sol
PW:S for rapture
Spirit Shell with archangel up (can do AA + DS -->PW:S for BT --> IF+ SS --> PoH x3/4 depending on haste --> DS again)
PW:S on tanks **
PoM when it'll bounce
PW:S outside of Lucidity or Rapture, non tank targets
Smite.

*Offensively, penance is far better. Defensively should only be used in the most dire of situations. I never use it in this manner on farm, and I used it sparingly on Heroic Siegecrafter / Heroic Paragons because of intense tank damage. When used offensively, you get 3 individual smart heals (each volley.)
**PW:S on tanks when not LMG proc or rapture is defintely a use your brain moment. If there is tank damage, do it. If not, it's better to cast smite.
There are times where you would intelligently hold AA+DS rather than mash on CD, mostly for when desecrated weps fall into melee.
Twist of Fate is king, it also double dips from atonement.
Level 90 talent selection is critical, SS timing is critical, PW:S whoring with your lmg is...well, whoring but critical.
It is worthwhile to hold a smite or two, in favor of living AA/DS up perfectly. Omitting smites in favor of using better spells is beneficial in 2 ways: You use less mana, you have better DA generation. Do NOT get caught chain casting smites together outside of extremely low damage situations, for Penance/HF/DS/PW:S is often a much better choice. If you want to bring more damage, make sure your DS is cleaving, and penance/HF are still higher priority outside of glyph of smite simply because they hit harder.
