Faction Boosting for Evil Chars

[maultar]

Did "some" looking on here on this couldn't find what I needed.

I need to raise faction with Ogguk because vendors will not sell to me. So not much to go there but I don't know why they won't talk to me I'm evil, Dark Elf Innoruuk. They don't KOS but they won't sell to me.

My other desire is to be able to walk in to all freeport zones uninvised and buy from merchants. Now is just above the cut good enough or does having a higher faction (ally) get you cheaper prices? Same with Charisma? Better off just malking a human mule?

If I were to do it all myself no mules how does one go about raising faction with Ogguk and Freeport? Most efficient route please. Thanks in advance.
