Scarlet Monastery: Gold

Gold requires killing all 3 bosses and at least 40 enemies in under 13:00 minutes.

Be aware that the remainder of the Cathedral will pull with the last boss if you pull him without clearing.

Having just completed this, here's a few tips and facts from our run.

Setup:
Brewmaster Monk (tank)
Mistweaver Monk (healer (me))
Elemental Shaman (dps)
Survival Hunter (dps)
Frost Mage (dps)

Scarlet Monestary is rumored to be the hardest of all the challenge modes to complete with gold.
Personally we had alot of trouble with Siege of Niuzao.

Thrash pulls:
We cleared the very first pile of corpses to the left and then skipped right to the boss.
Killing the ghosts on his left hand first then pulling the boss.
While on the boss our dps killed the ghosts to the right, no tanking required if done right.
Finished off the boss.
We pulled the big thrash pull patrolling the corridor to the courtyard. in addition to those we grapped one of the neutral judicators and a single thrash mob from the group at the end of the corridor. We burned every cooldown and had the tank kite in order to kill them.
At the end of the corridor we popped our invis pots and used aspect of the pack and skipped all the way up to second boss by the water fountain.
We pulled the 2nd boss with everyone standing at melee but the hunter (to direct his flame AoE to him)
Then we ran between the thrash packs in front of the cathedral.
We pulled everything in the right side of the cathedral with Ring of Peace (it does wonders, believe me)
Then we took the right side in two pulls.
Finally we cleared the big pack with initiates and pulled the boss while most of them we're still alive.
We killed the boss...
We beat the timer by over a minute and got both gold and realm best score.

We popped timewarp at 1st and 3rd boss.
I was fistweaving at every oppotunity for a wooping 45k dps.
Ring of peace.... omg...
This was our third server best (having only completed 6 golds as of yet.)

Completing these Gold achievements rewards a teleport spell so you can quickly get to the instance when ever you want. These spells are fly-out spells, meaning they are grouped and only take one actionbar slot -that's nice. The fly-out group consists of:
