This is your more "traditional" Arms rotation and spec. There are many others that differ slightly and differ by quite a margin.
Rotation:
Keeping Rend up at all times is a must. Do not refresh Rend until the entire 18s duration expires so you don't miss out on any TfB procs / extra Rend damage.
Using your TfB procs as soon as you can is the way to go and should be your #2 priority. The proc lasts for 8 seconds but you can proc another TfB in 6 seconds (after 2 Rend ticks).
Make sure you use your Sudden Death procs efficiently; don't use them sub 30 rage or if Rend is about to tick off.
Bladestorm on each cooldown but keep your priorities straight (TfB / SD > Bladestorm).
As far as Mortal Strike is concerned you're going to be putting this into your rotation after you use every Sudden Death proc
or if you need a rage dump and the CD is up while waiting on other abilities to proc/come off cooldown.
Now what about your excess rage? What do you do with it all!?
Use Slam and Heroic Strike as your rage dump. There are plenty of GCD's (RNG pending) free to Slam away to your heart's content. In most cases using Slam is better than using Heroic Strike (queued attack (less control) vs casted attack (more control) ).
Mortal Strike is a great rage dump. The reason I say to use MS after a SD proc is because it'll give you that extra chance to proc SD, which is one of your most efficient usages of rage, ie it gives you the most damage per rage next to Overpower.
So in a combat situation it should look like this:
+combat
Bloodrage
Trinkets/Racials
/Cooldowns in general
Rend
(Sudden Death proc)
(TfB proc)
Mortal Strike
(Sudden Death proc)
(TfB proc) -> Bladestorm
(Sudden Death proc)
(TfB proc)
Slam Spam until Rend falls off or your next SD / TfB proc
etc, etc...

Glyphs:
Major:
Rending, Mortal Strike, Bladestorm
or
Rending, Mortal Strike, Execution
Minor:
Charge, Bloodrage, Battle
Macros:
Personally I don't use any macros for Arms. However if you feel like being extra lazy you can try out this macro:
/castrandom Mortal Strike, Slam, Heroic Strike, Execute, Overpower
You'll have to manually cast Rend and Bladestorm/Sweeping Strikes.
FAQ:
What about ArP vs STR??

Is a consolidated post regarding ArP vs STR with some of my own personal insight and live testing.
In short;
Q u o t e:
Once you can hit 40% ArP including Battle Stance passively (no gems), then swap your STR gems to ArP.
Until then, ride the STR train.
Q u o t e:
DISCLAIMER:
I would STRONGLY advise AGAINST gemming all ArP until you have at LEAST 30% (40% including Battle Stance) PASSIVE ArP.
Until that point:
STR > ArP
After you hit that threshold...as long as you can maintain hit and expertise cap along with ~35% unbuffed crit then go re-gem ArP.
Amg. What's the BiS!?
BiS for Orcs and non-Orcs will be coming around soon enough. Going through the loot options with Darkfade later this week and I'll post our results.
Feel free to ask any other questions, I'll be sure to at least attempt to answer them.
