Looks pretty good to me. Let's throw some stuff together:
Fully buffs, Kings + AI + DS + Elixir of Mastery + Elixir of Draenic Wisdom:
Intellect: 645
Spirit: 813
Spirit Regen: 289mp5 while casting
Total Regen: 317mp5
That may or may not be the elixirs you're using, but those maximize regen.
By switching to Malorne helm, you drop 4mp5 from spirit and 21 raw healing, but gain 10mp5 and the proc (don't know how you heal, but it's safe to assume at least 8-10mp5 from that). That is discounting Innervate, but in my experience Innervates rarely go to the druids themselves. If you want more regen, Malorne is the way to go.
For your weapon, versus your current one
- Solarian staff: +5mp5 while casting, +67healing
- Light's Justice + Badge Offhand: -3mp5 +89healing
I'd say Solarian's staff is better, I think it's hard to justify losing 8mp5 for only 22 healing. If Solarian is quite a ways off for you, I definitely *would* get Light's + badges, though, that's a huge boost in healing for a tiny drop in regen.
If you're really concerned about healing, Belt of the Long Road boosts your regen by a little (4) and healing by a really large chunk (27), and is definitely worth dropping epic gems in. Same with the robes from badges or ZA (ZA has higher regen, badges higher healing). The bracers from Heroic MrT and the gloves from badges both give a good boost to your healing, though not a whole lot for regen. With your current gear, the badges ring would boost healing by 22 and have a tiny boost in regen (2) despite the lack of spirit.
Fake edit: Damn, after doing all the stuff I realized I forgot fishy sticks and Improved DS. Oh well.
