Ok finally 80 and all that jazz, a few question about Heroic druid healing -I've not stepped into a heroic 80 dungeon yet, and I would like to gear myself to be nax ready eventually. My guild doesn't do nax in house because we don't have enough people for it and we aren't focused on raiding, but a lot of people in my LS in FFXI have converted to WoW also , so in a month or three we'll be seeing it and then ulduar.

First off, how much MP is considerered "Decent" when healing for heroics as a druid? Right now I sit on 14.5k after Mark of the Wild, 2 purps and a few blues here and there. From my understanding it's not as necessary as other healers since we have a few MP management tools and hots.
What should I be looking for in an order of priority? Currently my priority is Spellpower>int/spirit>mp/5>nothing else as I don't know what I should be looking for.
How much mp/5 is considered decent for going up to heroics?
So far I feel confident enough in most normal dungeons, I heal fine unless it's something a little tricky like Skadi in U.P. Today I just healed through the supernova from the boss in HoL reg and it wasn't taxing on me at all, I'm just not all that confident in joining a heroic pug as I have no idea how hard/insane it is compared to normal.
Here's my current spell stats
Here's my current gear/talents.
The World of Warcraft Armory
I have a few in balance for when I solo, feel free to critizise, I won't be upset

If you're going to reccomend me gear though I'd rather you suggest anything from a reg dungeon instead of AH/Crafted/Heroic because I'm still saving up for epic flying and I have not entered a heroic!
If you feel I've made a bad talent choice, please explain why it is bad. On the topic of talents - I am thinking of redoing them (obviously) and want to include the one that gives me a spirit boost as I find my spirit abysmal, however I hear I shouldn't be doing anything regarding spirit as they're changing how it works as mp/5 soon? Please explain :D
