Monk - Metal pipe questions

[Anxarcule]

I'm 3 yellows in 54 at the moment and considering going to KC with my shaman buddy once we hit 55 to camp the pipe (both will hit 55 around the same time). At this point I'd be happy to buy both pipes but only see the Chardok pipe for sale so will try and camp KC. A few questions:

1. I've never been in the zone - how difficult is it to fight our way to the camp?
2. Can we invis our way there (maybe the pathing has more living creatures than undead)?
3. Once in the room, are there multiple spawns or is it a single spawn? If multiple are they easy to split?
4. Can a non-twinked Monk/Shaman 55 duo expect to be able to do this?
5. If no to the above, are there any other drops in the vicinity of the pawbuster that I can entice other classes to join the camp?
6. For PvP avoidance - is it easy to gain faction with mobs in this zone? Meaning, can a player with faction go searching in the zone to find and kill us, or if we are deep inside they need to fight their way to us.

Thanks
