Sightstone is a must on a support. Best to rush it or get it after you upgrade your gold income.

Face of the Mountain is great with Nunu's naturally high health. You could replace Warmog's Armor or Randuin's Omen with a Frozen Heart, as the mana will help Nunu greatly and the aura feels nice with Nunu's other attack speed slows (It also slows Vayne's aa even if she isn't attacking you, for more than Randuin's.)

A fantastic alternative to Spirit Visage is Banshee's Veil, even after the nerfs. Face of the Mountain, with consume and Veil's passive (and Warmog's if you get it), should be more than enough sustain. Veil's can also potentially make it harder for enemies to cancel your ult. Frozen Heart will compensate for the lost CDR from Spirit Visage.

And you forgot one item. Zeke's Herald. Support Nunu is mainly about his ADC. Zeke's is one of (I think the only) items that wasn't touched when life steal was being nerfed, and now grants more LS than a Vamp Scepter. Zeke's, with Blood Boil, gives your ADC a massive amount of free* stats. Zeke's also allows Nunu to be more useful during his ult, and gives him some tankiness and CDR.

Boots depend mostly on your matchup, so Mercury's Treads may not always be the best option.

CDR runes are pointless, and Intelligence is nice, but part of it will be wasted. With Frozen Heart (20% CDR), Face of the Mountain (10% CDR), and Zeke's Herald (20% CDR) already brings you over the cap. Buying Spirit Visage over Frozen Heart or Zeke's Herald will just meet the cap.
