Question about SoulFire MQ and faction

[DazenGuile]

I recently looted the Glowing Sword Hilt from Xicotl in MM. I would like to MQ it to my friend who has the necessary Priests of Life faction.

Do I need to raise my faction as well? Or can I give Brother Hayle the hilt, and have him get the sword when he turns in the other 3 items without raising my own faction?

If I do have to raise faction, are the Werewolf Hunter turn ins bigger than the 2 gp turn ins in Qeynos? I'd really rather not do 2000+ turn ins to get warmly if I can avoid it.
