I'm copycat!
From the very beginning, there are five Outlands dailies that can be done for the Offensive. Those dailies should always be available. I don't know if they assist in reclaiming the various areas in Sun's Reach.
* Gaining the Advantage - Quests - World of Warcraft - Gaining the Advantage
* Sunfury Attack Plans - Quests - World of Warcraft - Sunfury Attack Plans
* The Multiphase Survey - Quests - World of Warcraft - The Multi-Whatever Something-or-Other Survey
* Blood for Blood - Quests - World of Warcraft - Blood for Blood
* Blast the Gateway - Quests - World of Warcraft - Blast the Gateway
For the actual reclamation project and the dailies associated with each phase. Note that some of the dailies can still be completed after they finish, replacements are marked with a ---
Phase 1 - Recovering Sun's Reach Sanctum
* Erratic Behavior - Quests - World of Warcraft - Erratic Behavior
* The Sanctum Wards - Quests - World of Warcraft - The Sanctum Wards

Phase 2a - Building the portal to the Sunwell from Shattrath
* Intercepting the Mana Cells - Quests - World of Warcraft - Intercepting the Mana Cells
--- Maintaining the Sunwell Portal - Quests - World of Warcraft - Maintaining the Sunwell Portal

Phase 3 - Recovering the Sun's Reach Harbor (All of this is speculation)
* The Air Strikes Must Continue - Quests - World of Warcraft - The Air Strikes Must Continue (Replacing Distraction at the Dead Scar)

* Crush the Dawnblade - Quests - World of Warcraft - Crush the Dawnblade (Replaces Taking the Harbor)
* Discovering Your Roots - Quests - World of Warcraft - Discovering Your Roots - Creates a reagent/special items vendor
