Kelnoen,
First of all like everyone said it depends on how well the rest of your group is. If they're very well geared, you can go in there naked and still clear the place.
In terms of spec, for beginning raiding, 41/20/00 is definitely the spec to go, period. At this stage you don't have enough bonuses for MM to work.
Looking at your spec, you want to:
-Pump 1 point into Endurance Training.
-Take out all 3 points from Thick Hide.
-Take 1 out of Frenzy
-Pump 2 into Animal Handler, just like how you need +Hit, the +Hit for you pet is crucial as well.
-Finish 5/5 in Mortal Shots in MM
In terms of your gear, you're not quite there yet if your whole group is new.
You hit rating at 116 which is fine for now, but just know the cap is 142.
If you're into PvP at all, PvP 1 day for the Vindicator Bracers, they're great even for PvE. Then PvP 2 days each for the Guardian Belt as well as the Vindicator Boots.
Those 3 are the most beneficial PvP pieces for PvE. Also, if you do arenas at all, do 10 matches a week, and in about 3-4 weeks once you get 1000 points, you can get the
Vengeful Gladiator's Waraxe which will last you for a really long time.
Also, the hunter's D3 Set - Beastlord Armor is great going into Kara with as well. The pieces all drop from normal instances so it shouldn't be that hard.
