Build 13066 does change everything.

Or Not :P
You can find all the details on MMO Champion, but for Holy Paladins here is the only change that concern you:

Spiritual Focus no longer gives you hit based on your Spirit. Renamed to Paragon of Virtue - Reduces the cooldown of your Divine Protection by 10/20 sec and the cooldown of your Avenging Wrath by 30/60 sec.
Enlightened Judgements now also grants hit rating equal to 50/100% of any Spirit gained from items or effects.

Nothing linked to PvE though Spiritual Focus can have PvE uses, they are very limited. It won't change the 31/5/5 build I gave before much, though if Enlightened Judgements grant range to our judgements as the mmo talent calculator says, then it'll replace the 2 points into the Improved Judgements ret talent. As the calculator has changed, you can find the new build here. It will be a 33/5/3 or a 31/5/5 depending on range being linked to Enlightened Judgements or not.

For another view of our new talents, you can find a Prot analysis of build 13033 on Rhidach website Righteous Defense.
If you want more analysis of Holy Talents and skills, I'd advise you to read the detailed article on Paladin Schmaladin and the healing "tips" and comments on Blessing of Kings.

See you soon hopefully patch 4.0.1 will hit live soon, for good and bad :)
