Aww. Sure I'll try to help, you should also ask PC and Coprophagia as those guys are also helpful. I'll try to list some of the macros I use.
You can indeed cast Holy Shock and judgement together, simple as:
/cast Judgement
/cast Holy Shock
You can also add more things to it like this, but then you'll need to spam like crazy:
#Show Avenging Wrath
/cast Avenging Wrath
/use Hex Shrunken Head
/use Icon of the Silver Crescent
/use Destruction Potion
/use Super Sapper Charge
/cast Judgement
/cast Holy Shock
These are some useful arena macros that allow you to automatically cast these spells on your 2v2 partner without targetting him.
#showtooltip
/cast [target=party1, exists] Blessing of Protection
#showtooltip
/cast [target=party1, exists] Blessing of Freedom
#showtooltip
/cast [target=party1, exists] Blessing of Sacrifice(Rank 4)
Libram swapping macros:
This one is for Holy.
#showtooltip judgement
#show judgement
/equip Tome of the Lightbringer
/cast Judgement
This one is for Shockadin.
#showtooltip Judgement
#show Judgement
/equip Libram of Divine Purpose
/cast Judgement
This one is for Ret.
#showtooltip judgement
#show judgement
/equip Libram of Divine Judgement
/cast Judgement
Consecration libram macro:
#showtooptil Consecration
#show Consecration
/equip Libram of the Eternal Rest
/use Oil of Immolation (optional)
/cast Consecration
Seal libram macro:
#showtooltip Seal of Righteousness
/equip Libram of Divine Purpose
/use Oil of Immolation (optional)
/cast Seal of Righteousness
Heal libram macros. When I'm ret I add /equip healing mace/healing shield, and then I have a button to switch back to my 2her.
#showtooltip flash of light
#show flash of light
/equip Brutal Gladiator's Libram of Justice
/cast Flash of Light(Rank 7)
/script CombatLogClearEntries()
#showtooltip Holy Light
#show Holy Light
/equip Libram of Mending
/cast Holy Light(Rank 11)
/script CombatLogClearEntries()
I also have a rank 1 heal in case I want the 30 second mp5 boost and don't want to waste my mana.
Crusader strike libram macro:
#showtooltip Crusader Strike
#show Crusader Strike
/equip Libram of Righteous Power
/startattack
/cast Crusader Strike
I also recommend getting Fiery Blaze on your weapon and using Shadow Oil on your weapon too. They scale with SP and give you a huge bonus in damage, but I stopped using them since people said it was cheating. But the way I look at is if the SP's get the bugged trinket I can use my bugged items. >:D
That's basically it, really simple macros to use! If you make a shockadin then the best piece of advice I can give you is to try and use your melee as much as you can, people always underrate that 600-1000 dmg a hit, it really adds up over the course of a fight. Try to remember to re-seal right after casting judgement. Other than that it's really easy to play.
The final piece of advice I can give you is to check out my Shockadin tutorial video on youtube:
