(Minor spoilers ahead; probably safe to read)
Woah.
I started running this module just last week :)
I'm basically planning to wing it, and simply substitute monsters for monsters without worrying too much about the details. For example if the module is just using Gnolls, I just use Gnolls. I'm trying to keep the CR's about the same - there's a dragon who has mysteriously lost an age category going from D&D to Pathfinder - but otherwise am keeping them the same.
As for the NPC's - I'm eyeballing them and just running with the numbers which are pretty much right for D&D 3.0, but wrong for 3.5 anyway. That will more than likely have to change when/if NPC's actually join the party as I'll have to stat out the NPC properly.
I'm not aware of an already existing algorithm/program to convert "x-level" D&D NPCs from 3.5 to Pathfinder, let alone 3.0 to Pathfinder. I think you and I have some work ahead of us :)
While I'm on the subject (and I'm going to make a thread on this) - have you had any thoughts on the "Force" domain that is listed in that book?
