Rogue Epic Question

[Kalbren]

Hiya folks, so I realize the rogue MQ is "cheap" but for someone whose highest level toon is 42, 20k is still a bit spendy. So I have a 34 rogue now and I was wondering about the epic. I see the first step to get the pack requires lvl 51. Though later in the walkthrough it mentions if you have high enough faction you can just spawn the turning NPC by saying something.

Does anyone know what faction I'd need to grind up for that to happen?

Also anyone have a suggestion on when I have a somewhat reasonable chance of succeeding with pickpocket steps?

I'm kindda wanting to do the foot work here and get my epic started soon as I can.

Thanks!
