My Paladin was my raiding main for a long time. Heading into the Ulduar patch he was full best in slot as Ret. We had a healer shortage so he was healing as we started into Ulduar. With it looking like my move to healing would be long term, I geared out my priest in a few pugs and made him my main instead. I just like to heal on my priest more than I do as a Paladin. With that change, my Paladin sat and his gear fell behind. I decided its time to refresh his gear.
I have gotten him into a few runs to help out a guild group or a friend when my main was already saved. Last week I got into a friends ToC25 run where I won a new weapon and purchased 2 trophies. After that run I had just enough emblems to get a pirce of gear with one of those trophies. I was almost sad to put my Betrayer down until I equipped my new weapon mid run and saw the results. That run is what pushed me to update things.
I downloaded an old friend of mine to help me out. Rawr. With Rawr I can just point it my my armory and plug in any other items I have and it will assemble the optimal set of gear for me. It will balance hit for me and pick the gems needed. It will gem for the socket bonus if its worth it or skip it if its not. I have a good idea of what it will pick for things so I can verify whats going on. Because my guy does not have any epic gems yet, this will be a big shopping list. (There are also a few upgrades that I received and just banked at the time so they have no enchants or gems in them)

Rawr
Here are the enchants that I need to get mats for: Berserking, Crusher, Assult to ring, Icewalker, Fur lining, +10 Stats to chest, leg patch, and an Eternal Belt Buckle. I also need lots of gems. I know a JC that can cut all the cuts I need. A few of those enchants are for a few things I was thinking about crafting. An important step would be to decide if its worth crafting a few things. So lets look at the options.
[Valorous Redemption Breastplate] (354.78) -> [Titanium Razorplate] (475.36)
[Bracers of Unrelenting Attack] (323.85) -> [Crusader's Dragonscale Bracers] (368.75)
[Girdle of Razuvious] (275.86) -> [Belt of the Titans] (320.5)
[Melancholy Sabatons] (283.28) -> [Battlelord's Plate Boots] (307.82)
Those numbers are the dps calculations according to Rawr. I know they shift around based on different items equipped. To get these I equipped all the upgrades and ran the optimizer. I left the items in and just checked the comparison in the chart for the DPS values. I know these will not be exact this way, but the relative differences is what I’m looking for. Here is a chart with more details.
If I was a serious raider on this character in our guild I would have all of these things crafted in a heartbeat. I would also do that if I was trying to join a guild with him. Because I am not doing either one of those with him I wanted to break down the value of each upgrade. The chest and wrist are both i245 items. Those items also give me the best return and will last me the longest. The only item I am going to hold off on are the Boots.
After I did all this work I went back to look for other easy upgrades for my belt and I discovered one from emblems called [The Belt of the Singing Blade]. I know I have the emblems so that just saved me 2300 gold. I think I can build my shopping list now.
Craftables (5776.40 Gold)
10 Titansteel Bar
12 Crusader Orb
56 Saronite Ore
6 Arctic Fur
8 Eternal Water
1 Eternal Air
40 Icy Dragonscale
Enchants (1118 Gold)
48 Infinite Dust
9 Greater Cosmic Essence
9 Dream Shard
14 Abyss Crystal
1 Arctic Fur
1 Crystalized Water
2 Nerubian Chitin
Gems (1800)
1 Prismatic (+10 stats)
8 Bold Cardinal Ruby (20 str)
3 Etched Ametrine (+10 str / +10 hit)
1 Relentless Earthsiege Diamond
This puts my upgrade cost around 9,000 gold. Checking my numbers in Rawr before and after gives me a 11% dps increase. Having all this information in front of me I can break down where I am getting this increase from. Just by enchanting my gear that needs it and getting better enchants gives me the largest increase at 5%. Replacing all my gems and putting gems in gear that needs it gives me another 3%. The last 3% is from crafting a chest piece, bracers, and buying a belt with emblems. It is interesting that correct enchants give the largest increase at the lowest cost.
Now to go spend some gold.
