Also consider that we are not very far from the next expansion. I've also been in the guilds falling apart/burned out Healer mode for awhile.
I've been extremely happy over the last month or so just noodling around on my healers (Warden included) making sure that they are all at 80 with 200 AA and a nice stack of shards in preparation for the next expansion.
I find not stressing over getting T4 gear pieces when guilds keep falling apart..in part cause healers are sick and tired of TSO raiding...and considering that none of the gear I might or might not get right now is going to matter in a few months.
When I stopped stressing over this, I'm liking it more

If T9 is more of the same, that'll be it for me, sad to say. I've put up with so much over the years, but it wears ya down. When it's not fun and you can't make it fun..time to go.
That said, I join with the rest of the posters in recommending Larry's posts. He's min/maxed Warden in pretty much every possible situation you can be in. If you can be spec'd for min/max everything else you will do will be easy.
Definitely start putting in for the 'easier' zones Deep Forge, etc to start building up shards. Wardens of all the healers have it a little easier with not being so gear dependant, but even so some of the harder zones are going to be tough on you till you get some of your gear.
It doesn't take very long at all to build up enough shards for a set of T2 gear. Work on getting your fabled weapon (can't remember if you said you had your mythical or not) at least.
And definitely start hitting up the researcher for some of your more important masters.
I might be dragging my own sense of burnout into interpretation of those looking for group, but it seems most people LFG want you to be all equipped so that they can do the zones in the minimum time possible. That's not to say that you won't be able to find a group or two that will be willing to help you out.
Don't worry about overloaded healing if you are just going to be grouping. If you can get an item with it, fine, if not..meh. It's not the incredible proc it once was. Like everything else, it's had it's bite removed
