First off, do you raid 25 mans or 10 mans? Cause if so it plays a big role in your heal style. I'm would assume 10 mans as thats what most people who most on this forum do, but you are using Glyph of LOD which is primarily a 25 man glyph so I'll judge you off that.
I'll help with your talents / glyphs first since gear is easy to obtain and doesn't measure skill or your abilities as a player to make smart decisions
Glyphs / Talents
You use glyph of holy shock? Why? Glyph of Divine Favor is vastly superior in every situation. I wouldn't recommend glyph of holy shock unless perhaps you were a crit / mastery paladin which obviously you aren't
Next, you have an abundance of spirit more then I have and im 7/7 25man Heroic; 3 healing rag. I assume you are working on Heroic Rag since you have Glyph of Holy Wrath (I pray you don't just leave that glyph in out of laziness) so I would take out glyph of Divine Plea or Glyph of Light of Dawn and replace it with Divine Protection. All damage you take in that fight from a healer PoV is Magic and it happens quite frequently, most of which is a significant source of damage. And using DP every trap in P1, and every seed explosion in P2, and then it becomes invaluable when you have to follow the tank across the platform in P4 where you are building stacks up and aren't able to clear them for quite some time. I'd personally replace glyph of Divine plea as there is enough down time that fight to regen plenty.
Your talents are odd as well. Well the fact that you only put 1 point into Blessed Life. It has been debated before wither or not that talent is junk or not in PvE. I personally say it is not. Every ability heroic rag does can trigger it, but having only 1/2 is pointless. Now, some may disagree with me, but seeing as I did well over 580 pulls on him, and have killed him, and have been a boulder punter as a paladin I can tell you this. You DO NOT need Imp judge for that fight. His hit box in the first 3 phases is the size of Azeroth, so the only way you can be out of range to judge is if you stand in the far back of the platform which does 1 of 2 things, puts you in a position where Engulfing Flame can and WILL hit you; or you are pretty much saying "Hit me with Wrath I wanna go lava swimming" If you take a look at this
picture of rags platform you can see a perfect spot to stand. It is right in between the 1st and 2nd Engulfing zones, practically still in his melee hit box, and save from the melee knockbacl/silence.
So you can drop the point in Imp Judge and place it in Blessed Life to make it 2/2. Now, its strictly a personal preference but I don't pick up Sacred Cleansing in a 25 man setting. Why? Cause Priests can dispel magic without a wasted talent, and can do it at a lesser mana cost then us. This can be argued either way, but picking up a talent for just one mechanic in the entire raid which is easily avoidable is a waste compared to an obvious throughput talent.
Gear/Gems/Enchants/Reforges
Now I notice that you have some heroic pieces, but I hope you're not going right for ILevel. You are not at the 1859 haste cap which is a significant throughput talent, there are multiple things you can do to fix this.
1) Get the chest of Alys, or even the chest off Heroic Halfus (PuG's can do this blindfolded)
2) Drape of the Twins from the Twin dragons in BoT. Granted this isnt as accessible to do on Heroic with a pug cause it requires a brain, so It'll be last on the upgrade list.
3) The Tier Helm from Normal Rag is far superior to the 391 you have on (Unless you are far beyond haste cap)
Doing those will give you the haste you need to reach the cap
Heroic Eyes is pretty crap; It has the LONG 45 second ICD, and on top of that can proc at the worst times and completely waste the proc. I'd switch to either Heroic Fall of Mortality, or get DMC: Tsunami. Preferably Tsunami as it offers passive Regen / Proc (Unless you are good with tracking buffs to use with DP)
To answer your main question though "Is the 4pc good at all" No it's not. Compared to the other healers ours does a small chunk of our healing ~5% on a good rng attempt. Honestly it's only worth getting if you have all 4 pc's of heroic tier just like last tier. The int that you will gain from Non Heroic Tier pieces will make up for it (If you are good on haste cap that is)
