Pally in a Duo scenarioFollow

Hello. I'm fairly new to WoW and very new to playing a pally, so your help will be much appreciated.

My question pertains to where I should place my Talent points. Here's the scenario:

I'm a 33 Pally and Duo with my friend who is a Tauren Warrior. We have good gear with enchants, so I find that I rarely have to throw heals on my friend. The plan is that he is the tank, and I am DPS/heals. I'm using 2H weapons and am focusing my gear primarily around Agi and Str, followed by Int. Also, My pally is an Alchemist, so my buddy and I always have elixir buffs up.

I've recently decided to respec because I had 12 points in holy, but I feel that I only need 5 there for Divine Strength. I have 5/5 Imp BoM, 2/2 Imp Judgement, 3/3 SotC, and 1/1 SoC.

So here is where I am stuck with what to do with my 8 remaining TP. I find that although I am doing awesome damage, I miss a lot. I want to throw 3/3 points into Precision, but since my buddy is such a great tank, 5/5 Imp Devotion Aura seems like a waste of 5 points. Should I grab precision, or stick the points in Ret?

I should add that the purpose of this character is to be a high level Alchemist, so my friend and I arent really interested in doing much more with these characters than leveling very quickly.

Thanks!

yaya, Ret all the way if you are questing with a warrior buddy. I wouldn't put a point anywhere else until you get Crusader strike, then I'd probably still stick with the ret tree and fill in some other cool sounding talents.

Thanks for the advice, I'll just keep plowing through the Ret tree for now. I'll definitely take a look at Shockadin too :)

Shadow Priest? Nah, I like skewering things with my polearms >:)
