The Empire of Zul'Drak

Around 98/100 is what you'll probably have if you've done all the non-dungeon quests save for the Amphitheater of Anguish. There are six quests in the Amphitheater line, not including the lead-in, The Champion's Call!, which will put you above the requirement without having to step foot in an instance. In fact, I'm pretty sure the dungeon quests don't count toward this achievement.

As an aside, I'd like to mention a few other quests that you may not have completed and caused you to come up short. In addition to the Amphitheater, there are four other group quests, some of which you may be able to do by yourself:

• 
  
• WANTED: Ragemane's Flipper (3)
• 
  
• Malas the Corrupter (2)
• 
  
• The Gods Have Spoken (3)
• 
  
• Convocation at Zol'Heb (3)
• 
  

There's also the quest Feedin' Da Goolz, which you can only do while you're under the effects of the [item=38699]. I don't believe it's possible to obtain that once you've completed [npc=28518] line.

Don't worry if you missed a few of the breadcrumb quests. They don't count toward the Achievement score, so passing them up will only lose you a little XP and gold.

For Horde Loremaster:

All soloed on my alt 110 ilvl 934 Guardian Druid. If you’re deciding to do loremaster later in the game like me and you’re starting the zone fresh, I highly suggest doing it on a druid because you can kill and instant fly off, makes things go by so much faster.

All I did was follow around the large bold exclamation point on the map. Sometimes the quests are mixed and it makes you run around back and forth, but so be it. This is still minimum list of quests to do, everything else is a side quest.
