It really depends, right now end-game people will want you for innervate, which means pushing 31 points into restoration... I pesronally didn't go this way so far, but I'm only level 50 so I've gota bit to go before onyxia and molten core.
But for leveling things are different, I would recommend putting 20 points into balance at first, for swiftshifting and talents that boost damage from spells, as early on you'll be using a lot of spells.
Definetely atleast 11 into feral for charge, extremely important when grinding caster mobs to keep them from casting (walk forward till they start casting, step back and charge, repeat whenever they start casting).
From there you'll already be level 40 and you'll probably know what you want to do afterwards and can make your own decisions.
Also, patch 1.7 is due soon, so don't worry too much aswe'll be getting a free respec and a completely new talent chart
