4pc t10 is amazing in 25 mans. You can get it for 10mans, but it generally won't be worth the loss in haste.
Speaking of haste, get more. You're running without CF, so you need at least 856 haste to get your gcd down to 1 second. And if you're not running with both a moonkin (or ret paladin) and an ele shaman, then that number needs to be even higher.
Your spec isn't awful, but it's odd. I would really recommend 2/3 in subtlety instead of the wasted points in Furor. You'd be surprised but there are one or two fights (Valith, Rotface) where your healing threat can be a serious issue for tanks. Get 3/3 in Revitalize, it's a great talent that only a resto druid can bring.
Glyph of Rebirth is... good, sort of, for... well. Not really. It's a waste of a glyph spot, to be honest. Most druids run with glyph of Wild Growth, but if you're only running 10 mans, glyph of Nourish or glyph of Rejuv would be better.
Gear wise, get rid of Talisman of Resurgence. It's worse than... almost every epic trinket out there. Purified Lunar Dust is a good trinket to get if you don't have access to Solace or Althor's. Hell, even Je'tze's Bell would probably be better. Your cloak isn't good for us at all. You're running (3pc) 2pc t10 and 2pc t9, both of which are extremely lack-luster. I'd start picking up offpieces to replace them. Speaking of t10, you bought the wrong pieces full on. If you wanted 2pc, the gloves and the pants were the pieces to get, since they have haste.
Gem-wise, never ever gem int when you reach Ulduar-and-beyond level gear. In yellow or red sockets, gem 12sp/10 haste until you get a good amount of haste, at least 800. In blue sockets, if the socket bonus is good (7 sp or better), gem it with spell power/spirit. Otherwise, put another sp/haste gem in there. Get the Chance on Cast to restore Mana meta gem.
