There is a decent guide on PLD stats and priorities, but a quick run down would be something like: get your hp to around 4k (general consensus for safety net), double meld enmity to your sword and belt asap, these 2 things and you'll be set to really tackle endgame content.
Most head slots are worthless so get what you want, however a quick and easy filler is the Militia Armet, 100% drop from 60k chest in Aleport I believe. Acc is also a personal preference, it does suck missing a phalanx at the start so DD have to wait longer. Militia choker is a sizable upgrade however unless you manage to get top 3 provisioner, its really hard trying to get this by relying only on the 60k chest (im up to 0/45).
Here is a link I found about enmity which I found interesting.

While it appears most of it deals with War, the key part is
[PLD] are so much more heavily ability based meaning enmity trumps dps for pure threat since there is no known stat that increases enmity from using abilities (outside of WS's that is). I'd suggest foregoing anything with +enmity of 10 or less, as this won't make a significant impact at the start of your endgame career, unless you run with a fully developed endgame LS and need all the +enmity you can get.
AoE is Pld's weakness, I for 1 find it a ton easier to AoE tank as Gla even though they tend to be squishier. Gla can hold anything better than a War can, and both Gla and Pld suck for AoE damage.
1 last note, drop Vit and Def asap, you need to stack way too much to get a significant boost, and since Gil seems to be a hurdle for you there is no possible way you'll get enough to come out ahead. I don't suggest Vit/Def/M.eva or any of the other defensive stats until the latter parts of your build, in which you've got plenty of hp and enmity you can work with other stats.
Earrings are also up for debate, flames have a decent GC 1 if you can work in the bonus. There is also the rose gold earring 25(30)hp/15 hp but super tough to hq, stonewall for +10 enmity and decent defense, or a dated electrum should you want eva.
However it does come down to what exactly you're tanking, be it a primal where enmity and hp is needed, miser where its a burnfest, or CC (the boss not the instance) or H1's where hp n survival are key. There really isn't a "1 size fits all" tank set, but you can get by with following hp and enmity, even succeed at speed-runs.
