Before I can give you accurate answers I need to know what buffs they want you to bring.
Is it specifically Trauma becuase your raid does not have a bear?
Is it Blood Frenzy because your raid lacks combat rogues?
Is it Improved Demo Shout because your raid lacks paladins with vindication?
Is it Piercing Howl because you don't have a fury warrior or two to use it on Valks during p2 of LK?
Is it Commanding presence because your raid feels that they need the extra health?
To fully help you with the spec I would need to know these things but I can tell you what you don't need regardless of what buffs they want you to bring.
Deflection is a tank talent not a dps talent, you can throw those points into Imp Heroic Strike. Is Heroic Strike a rage dump? Yep it sure is but the more often you can use it without rage starving yourself increases your dps.
Second Wind is a pvp talent, put those points into Imp Slam reducing the cast on slam to .5 is a nice dps boost...in fact it is recommended to never use slam unless you have imp slam or a blood surge proc if you are fury.
That extra point from deflection, use that for your final point in Wrecking Crew.
Unless things have changed dramatically since I played arms as an offspec in Ulduar
Make sure rend has near 100% up time but do not clip the last tick and lose a TfB proc.
Keep MS on CD, TfB and SD procs have longish durations so use them when MS is on CD not instead of.
Also change the Execute glyph to glyph of Bladestorm and only hold BS in reserve for things like Bone Spikes, Valks you get the idea. Other wise keep it on CD as well.
