Advice for faction grinding on Shaman epic

[Rastignac]

1) Can anyone direct me to a good guide explaining how to do the quest through faction? Most of the ones I've found are confusing.

2) Is it possible/advisable to grind in CoM at this point? Or will I just get murdered constantly (I'm level 40)

basically trying to get a head start on this since I'm guildless and probs can't do the quest in the traditional way.
