So, I'll get the snowball rolling.
For PvP gear, I'm a survivability freak. I was an early adapter to Tivoli's old armor priest school, and spent far too much DKP on tank upgrades back in the day. I expect most strong teams to either kill or disable the healer rather than outdps your heal output, so raw output comes secondary to survival.
Through some calculations, I reached the following priorities for the main survival stats:
30 Stamina = 40 Resilience = 500 armor
Any such calculation has to take some pretty hefty assumptions, and as far as I can remember this is what I used:
- Effective HP 20000 - Starting from a base of ~10-11k, I expect to be able to heal myself/be healed for close to 10k against a decent team, between shields, PoM, Desperate Prayer and normal heals. Poor assist trains will allow me to have far higher effective hp, but I prefer to assume the opposition is competent, and place high priority on surviving the initial burst.
- Roughly 20% of hits taken are crits. This is a very hard number to estimate due to Blessed Resilience and depends heavily on opposing classes, but I feel it was a fair assumption, erring a bit on the safe side to avoid instagibs.
- Roughly 75% of damage taken is physical. Again a hard number to estimate, but we have to pick one to reach any results. With proper positioning this should be doable. The actual number here turns out to be relatively unimportant, since armor with the new mitigation formula turns out to be a far less efficient stat to focus on than stamina and resilience, even with such a high percentage of physical damage.
The other stats are harder to quantify, and I need some experience to see how I will adjust my gear to them. In general I rate intellect and +healing as the only casting stats worth looking at, but seem to get decent amounts of it even if I focus heavily on the survival aspect.
The pre-season gear I am aiming at is this:

The gear choices are to some extent influenced by what gear I have, and it's focused on not spending a ton of cash on things that will be upgraded with arena gear. The most expensive piece to obtain by far is the Unyielding Girdle, but that will be the belt of choice for a long time. Enchants also take long term cost efficiency into consideration.
CTProfiles won't show gems, but the only notable ones are Powerful Earthstorm Diamond for the head piece, and lots of +9 sta gems in the available slots. Shoulders and bracers in particular have useless socket bonuses, so you can stick all blue gems in them to reach the 5 gem requirement. +12 sta gems are available if you feel rich, and bracers for instance will be worn for a long time, so you can probably afford it there.
For Spec, I see a few preferred specialized specs:
Holy based:

Disc based:

Both those specs have some very questionable points, as there just aren't enough "amazing" talents. There is a lot of room for minor improvement and tweaks. Both specs do grab Meditation to get Improved DS, both for dispel protection with an additional buff and some damage increase for your casters. The Disc based spec maxes SR to avoid getting PS dispelled.
For myself, I'll probably be going with the more raid friendly:
