I'm playing resto shaman KFC. It really helps if you and hunter can get a T2 from RBG's...but since the season is nearly over your probably haven't got time to do it.
1) I will use retal(Die by the Sword) to stay offensive. Sometimes I will use it with my swifty one shot macro to stop another warrior or Rogue from peeling me. Don't forget to use it vs caster cleaves also... 20% dmg reduction is nothing to be sniffed at. Also it's very good to use it when you get to about 20% hp because then you will probably heal up to 35% HP before it's over and your healer should be able to pick you up. I will use shield wall when I'm in a heap of trouble and my healer is CC'd and my partner cannot peel me. Also it's better to kite/LOS the enemies then use shield wall...but if you can't get away then use it. I will use rallying cry mostly to save my partners life. Only if I have nothing left to save myself will I use it to save myself.
2) I never use stormbolt/bloodbath, which I probably should vs some comps. I always use Avatar because the pressure it generates and the get out of roots is awesome. I will sometimes switch from warbringer to juggernaut if I'm going to train a mage. Vs GOD comp I'll use juggernaught to train the mage for the majority of the game. Also sometimes I'll switch to staggering shout from disrupting shout for melee cleaves like TSG.
3) Make sure you are putting as much damage into your CS's as possible. Save rage for when you have CS then dump it all into it. Try make sure you have a TFB stack before using HS. With out cooldowns you aren't going to hurt someone with out CC on their healer (unless they are stupidly out of LOS of their healer). So you want to burst when their healer is CC'd. Make sure you have a macro to intervene out of roots. I have 4 macros... one for each of my partners, one that will intervene any target that is friendly in front of me and one that places my mocking banner and intervene it (I have seperate bind for placing demo banner but the same macro will intervene it). Also call out for dispels when you need it. Sometimes your healer will miss it. Call out for freedom totem/master's call from your partners. You having up time on targets creates pressure. They need to understand that. You can stick on pretty much any target with the exception of druids because they can shapeshift and get away fairly easy (unless you stun them). Our mobility is fantastic and with the right from your partners you should have no problem.
4) http://www.veevsvaul...s-key-bindings/ - read and use these macros from veev...they really help a lot. (all the intervene macros are there) Also read his blog and look at his addons. I find his addon for telling me when my healer is scattered/lulabyed/stunned from a hunter invaluable to stop traps.
My advice here is mainly for 3's but some applies to 2's also. Don't read too much into 2's because sometimes you face rank 1 glads at 1800 mmr. People tank their rating to cap fast...no one cares about 2's. You want to concentrate on 3's and use 2's to cap/practice a bit.
I switch from defensive stance to battle stance quite a lot. Playing KFC you are very rarely the target (spell cleaves do go for you often though), so use battle stance for the extra rage which will turn into extra damage.
Gear is important and T2 is the most important thing u can get. But don't let it hold you back. You can reach 2k without the gear. Then you will start to struggle. We couldn't get past 2.1k without T2 weapons... we floated between 2k and 2.1k for quite a while. We got T2 and all of a sudden our skills improved
