Looks good, I'll definatly second the Qiqirn Sash +1 however, its the Best HMP belt a whm can get. HMP+3, the same you get from the AF 2 Belt which is Incredibly rare.
That piece if you get it, will be useable on Every job with Mp while you rest, Definatly worth the Investment.
As for Rings, It really depends on what race you are, and how low you want your HP to be.
Im a taru, so i went with Mana ring and Electrum, offering a 35+ to Mp while only loosing 20 Hp, just ofc always remember that once those Mp are used up, those rings are rather useless until you rest.
White Cape +1 will ride you all the way into the 60s, which you'll still use for Cure 5s. So its definatly a good investment.
As for throwing item, i Still use Fortune Egg as a 75, its free, offers me ~10-11 Mp and 1 Vit (which Slightly helps cures)
Right now Hedgehog Bomb is something like 900k and raising my Mp cap by ~20 is hardly a big deal when i rarely get below half Mp.
All the gear slots you mentioned while useful are hardly core gear pieces.
I would definatly say make sure to have a Light and Dark staff before investing in any of the pieces you mentioned if you do not already have them.
I might also Suggest you try a piece of Crow's gear, they are relativly cheap, but offer decent Emn- boosts. Im aware you are almost into AF levels, and WHm is VERY fortunate in they can Ride AF all the way to Blessed and Nobles. But if you find you pull a lot of hate, try a piece of Crows or 2.
Also make sure you have Seer's Tunic and Barons Slops, they are Invaluable while resting.
Hope this helps a bit~
