Lemme check first your arms tree:
- No anger management: U need more rage generated and fast, arenas don't last that much and u need as much as u can. Get it.
(its only 1 rage every 3 secs I have Endless rage my dmg generates enough rage so I dont need it)
- Blood Frenzy: I see this more a pve passive abilitie than a pvp one, as u mostly stay on bersk stance and sometimes rending a target on arena can make lose rage when u change stances, even if you have TM.
(Disagree, Blood Frenzy procs off rend and deep wounds abilities.You dont have to pop rend. Deep wounds is activated after a critical strike and therefore a high crit rate will proc Deep Wounds and as a result Blood frenzy. Its loads of dmg for 2 points vs 4 points in 2H weapon spec to get the same dmg increase)
- Imp Hamstring: Yeah might be useful on those pesky pillar dancers but you have piercing howl and your normal hamstring, you dont really need to stop at all the target, as your main mission in arena is to land MS on the enemy to avoid the heals and kill em fast.
(No I have found it very useful.With Mace spec actually your target remains CCd quite often.Dont forget Hamstring was nerfed)
- Imp MS: never tried it, I don't really see any use for it, if u have a high dps wep you should be ending your enemy's life fast enough. So extra time on MS is waste of points.
(in one minute you could land 10 MS on normal MS but 12 with Improved MS increasing your damage by 20% disregarding the +5% more dmg from the talent)
- Endless Rage: never tried it, too deep in the Arms tree to be useful IMO, for rage u have good talents on Fury tree.
Now your fury tree:
- Unbridled Wrath: Why not? This is an ez cheap source of rage generation on the tree why not picking it up.
(As I mentioned above, Endless rage makes it redundant as it generates enough rage to compensate for AM+UW)
- Imp Demo Shout: You will end mostly hitting clothies in arena, demo shout its more usefull if your target it's a high damage melee class (rogues, droods, warriors, retadins and even hunters) no need to put all the 5 points here, Id rather put em on booming voice to increase the time of your shouts and the range.
(True but so will the other melee so u need to debuff them and the incremental debuff is 120AP less which is quite important)
- Commanding Presence: U need to boost up your AP or your teams HP (which I do most of the time if the other MS warrior is not on the playing time) the most you can. More HP means more survival.
(Well you are right about survival but I can still boost their HP but not as much.I dont see that much difference though. As for AP, well Blood Frenzy increases all melee damage on that target by 4% which is significant so it takes care of dmg)
- Enrage: Can be very very very very useful if you have a fast 2H enchanted with Mongoose, in this case a mace will probably have 3.7 or 3.8 in their speed, with enrage that speed gets down a notch and gives you more swings per second, u can pop DW/Trinkets when u enrage to increase damage meaning that you will crit or do more white dmg with higher numbers.
(well yes but I am usually not targeted first to be enraged in Arenas and even when I am targeted I dont get enrage that often plus its only for 12 secs plus u need to be on the target and not CCd so its not wasted.Another important issue is that it doesnt stack with Death Wish it was nerfed you didnt know it?Making it less useful.)
- Imp cleave is a joke, and if you don't have Sweeping Strike even worst, SS gives you the ability to land for 10 swings damage to nearby opponents if you can enclose the opposite team in arena SS+WW+Cleave, doing MS, demo shout = lots of dead people. Or at least you will do a lot of AoE damage, if landed properly goodbye squishies.
(Cleave is not a joke at all, it does insane dmg cause its 120% increase to the 70 damage it generates therefore it adds an extra 84 dmg which is great- a total of 154 damage. Who told you its useless? read post on Improved Cleave. As for SS I agree its nice talent but the faster the weapon the better it gets and its better with Flurry but it has 30 secs CD and takes 30 rage. Cleave alone can do the job damn well)
- Imp Slam or Weapon Mastery: Kind of controversial now that blizz changed the disarm thing to diminishing returns, this I leave it up to you, Imp Slam when properly done, can crit very very high, (highest crit Ive gotten in arena is 3k), u just need to practice and learn how it works. Weapon mastery gives you the chance to avoid dodges, so your hits will land more successfully.
Im not a math freak nor I dig on theorycraft, but this Is what Ive learned thru all the time Ive been playing my warrior.
Check these specs, that are more common and more pvp/arena viable.
If u have any chain/item that reduces disarm:

If u have don't care about Imp Slam on pvp:
