If you really want the haste breakpoint then I suggest doing what Rafal says, gem more haste if needed, and make sure you have the haste enchant on your gloves too. His setup seems good as well. Sorta depends on your playstyle and raid comp too, and what other healers you're with. Some people run with closer to 11-12k spirit, I've seen others at 15k, or even 17k.
The point I was making earlier is that I wasn't at the 7613 breakpoint and still healed most of the heroic 10man fights... but at some point I started gemming and reforging to hit the 7613 mark, especially for heroic Megaera.
