Turenn, I very much appreciate that you are trying to expand our horizons here. I have a very well geared warrior and pally and I'd love to be able to use the warrior for heroics in addition to the pally.

Knowing a bit about how you macro your warrior is very helpful, but the sheer number of abilities you have to use is overwhelming to me at this point.

A quick inventory:

For Pallies I need Consecrate and Holy Shield as spammables during combat, Avenger's Shield to pull, and maybe the ranged taunt (Righteous Defense) if things go badly.

For Warriors it seems much more complex - Shoot/Throw or Charge to pull (and either only generates aggro on one mob), Heroic Strike, Revenge, Shield Slam (maybe all three of these are on one button as you said), Taunt (which isn't idiot-proof like the Pally taunt in that you'll be "charged for it" and it goes on cooldown even if you already have aggro from the mob AND warrior taunt isn't ranged), Thunder Clap, Cleave, and Challenging Shout and/or Mocking Blow if things go badly. All these are from your original post, but I would also think Shield Block would be crucial since that's the only way warriors will get close to uncrushable. To begin the fight you probably need your rage-generation ability (Bloodlust, I think) to generate some rage, too.

So 4 abilities in 4 keys for a pally, 11 abilities in 8 keys and one mouse-over for a warrior (assuming only one of the three pull methods are used regularly and that the mouse-over covers three abilities).

Each of those keys is extremely precious as they are the only way to tell my alts what they need to be doing the whole time.

I am very impressed that you are able to keep all this going on your warrior - that's very cool. But I guess at this point (having tried both) I'm either just not skilled enough or don't understand the full set-up of a warrior tank to use them effectively.

I'd love to hear more.
