Are you asking if I take the +2 bonus to attack roll and +2 dodge bonus to AC and Reflex saves, does it stack with the +2 morale bonus to hit, saves, and skill checks?
The answer is yes, because the Blessings of Fervor is an unnamed bonus to hit and the Heroism is a morale bonus so they stack. The Blessing of Fervor is a dodge bonus to reflex saves so it stacks with the +2 morlae bonus from Heroism.
The not stacking with Haste is in relation to the choice of getting the extra attack each round as a full round action.
