For Geoda on that particular fight he chose Sacred Shield since he was doing a ton of single target healing. Though Eternal Flame I would think does just as well when fully powered. Looking through that log, it seemed Tolzzy has Sacred Shield as well and according to this
ression he used it primarily on our warrior off tank. the main reason I think he used that spell instead of EF was probably becasue most of his holy power was going to LoD instead of WoG. While as I mentioned before, Geoda probably could have made good use of it since his WoG was more heavy. Though obviously he thought Sacred Shield would do better for him.
EDIT: To say something else, Sacred Shield is more useful on this fight for Tolzzy (AoE Healer) becasue both tanks are taking the same damage at the same time. So there is no tank switch and I'm not sure how Sacred shield acts with a Prot Pallys. To say the least, its pretty good on this fight since both tank tanke the same amount of damage at the same time and one already has sacred shield.
Though I have seen Tolzzy make good use of selfless healer on some fights (I think Heroic Will of the Emperor was one). IMO that tier of talents gives you a lot of choice for play styles and should be taken into consideration each time you want to try to improve your healing. Being able to use all 3 can greatly diversify your healing to make you adaptable to any encounter. To say the least, I know our paladins make use of both EF and Sacred Shield, and the occasional Selfless Healer for specific fights.
Also, on EF blanket, you definitely don't have to blanket, but remember all those HoT ticks from EF will transfer to your beacon target which can help steady tank damage. If you are using EF, you should probabl at least make use of it on people that need the WoG heal and the EF ticks are extra for your beacon.
EDIT again: Last thing to note. Even though spirit stacking may seem silly (I understand, because I played a resto druid from late wrath through early MoP, and I stacked pure intellect and almost reached a 190k passive mana pool in late cata, when the average was 150k~). But when MoP hit, and the intellect/Mana Pool change came into effect, spirit has just become a very necessary stat. With blues, you need to stack spirit. It is just the best way to go. Intellect and more spirit will come with gear. When you have more gear and can maintain a 10k-13k spirit pool and are comfortable, then I would say start making the intellect switch.
