Generally my rotation (for 2-3 elite group + normal adds) goes like this: avenger's shield into Hammer, consecration, holy wrath, hammer, judgement, hammer, either WoG or Shield (depending on how much damage i'm taking). If grand crusader triggers, I use it at the next GCD option.
I use my mouse button4 (or r) for taunting. That hammer toss that you can use at 20% hp is 1, and the 1 min CD stun is 2. C and V are my 'oh crap' buttons. Avenger's shield is bound to mouse 3. Q/E are my 'bread and butter' hotkeys, r/mouse4 are my taunts, F is my utility key (item 15 is my health pots).
Here's my macros.
Q /castsequence [mod] Judgement, Crusader's Strike; Hammer of Righteousness
E /castsequence reset=30 [mod] Shield of Righteousness; Consecration, Holy Wrath
R and mouse4 /cast [@targettarget, mod] Righteous Defense; Hand of Reckoning
F /cast [dead] Redemption; [@targettarget, harm] Word of Glory; [mod] 15; [help] Hand of Protection
V /cast [mod] Divine Shield; Lay on Hands
C /cast [mod] Hand of Freedom; Divine Protection
