People you don't have to do ANY faction work. For starters you can get the red headband by killing a monk trainie in FReeport, they drop it every time. As for the one in qeynos simply make a human monk and let him do the turns in. Every item for all the sash quests is droppable. Just farm them with your iksar and let your human monk do the turn in. You sometimes can find people selling the parts in bazaar if you want to save time, but most of the sash quest items are fairly easy to come by.
Also be prepared for the longest most annoying camps ever! Raster, Torgin, Drovalg, and Iksar Betrayer are all long tedious camps. Even at lvl 69 I needed help with the 2 Kunark mobs due to adds. In Karnors you get the Cleric mobs complete healing through the walls when you try to kill placeholders.
After that part its really not too bad.
Just use Sneak on the mob in eurdin (don't know if he is KOS or not, I don't think he is though).
EDIT
Oh and killing the quest mobs for the robe isn't always the best idea. Both of them (the one in Rathe, and one in SK) are undercons as they are flagged as guildmasters. The one in Rathe Mountains is uncommon spawn and neither of them drop the robe every time, in fact I hear its a rare drop. It took my 69 monk, and a well requiped lvl 70 Shadowknight useing harmtouch and disc to kill the one in rathe, and he didn't drop anything but a black sash (which is worthless).
