Not quite true. Take a look at the top warrior parse for the entire raid:

The majority of their damage is melee attacks, followed by Cleave and Heroic Strike, both of which deal their damage on your next auto attack. That means you get more of those abilities out by having more Haste.
No, not true at all.
For a Bear, you have two jobs:
- Generate obscene amounts of threat so everyone can pump out full DPS
- Tank obscene amounts of damage because you have a ridiculously high amount of armor and health
There is never a time where really you need both.
For generating threat, NOTHING exceeds Haste point for point. When it comes to arcanums, 1% Haste is vastly superior to 8 Strength or 8 Agility. This is because Haste is multiplicative, so using a Manual Crowd Pummeler, 2 Haste Arcanums, and a Minor Haste enchant on your gloves, actually reduces your attack speed to 1.62 attacks per second rather than just 1.63.
This haste is guaranteed, whereas Agility provides a chance to critically strike, which on average your threat by a percentage equal to your hit chance multiplied by your crit chance. You actually don’t get the full value of Crit Chance because you are attacking from the front and have a chance to be dodged, parried, and to miss.
Strength is similarly guaranteed, but the 16 attack power is a marginal 1.14 DPS increase, or 1.26 with Kings. Assuming you don’t use Haste enchants, but do use a Manual Crowd Pummeler, 1.26 * 1.67 = 2.1 more damage, or 5.33 more threat per second.
Haste, however, takes the same damage you already have (this is why I said it depends on your existing stats) and essentially increases it 1%. If I hit for 600 with Maul on average, I am dealing 359 DPS, or 911 TPS. With 1% Haste, that goes up to 363 DPS, or 922 TPS, which is 11 TPS.
For mitigating damage, Dodge vastly exceeds Agility in value. 8 Agility is only 8 armor, and 0.4% dodge. The armor from Agility does not scale with Bear Form or Thick Hide, meaning it is a flat 8 armor (a minuscule amount of extra mitigation, totally negligible), and the dodge it provides is quite clearly less, meaning 1% Dodge will reduce the most damage throughout a fight, on average.
