Wow, you sure got a lot in there! I made a fast Orc fixer (http://skyrim.nexusmods.com/downloads/file.php?id=8474). It only makes corrections, nothing new.
Exactly what was corrected:
Garakh was correctly linked to her (already existing) vendor chest, and given her own faction (ServicesLargashburBlacksmith). She is a proper blacksmith vendor now.
I don't know the form IDs, but I fixed some dialogue:
DialogueDushnikhYalHuntingScene02: Arob: "Patience my son. The hunter days not welcome...." changed to "The hunter DOES not welcome..."
I reversed the speakers on the following two dialogues:
DialogueNarzulburMauhulakhDushnamub2 (Mauhulakh was calling his son "Father")
DialogueNarzulburMulGadba1 (This was changed because of Gadba's dialogue "Mul is the smart one. I go where he tells me.")
I didn't catch the chieften/chieftain error, but I'll leave that out in deference to the USP.
The following SHOULD be changed, but I've left it as it was (so far). What do you think?
DialogueDushnikhYalHuntingScene01: Arob: "The air has the smell of beasts. The hunt is good today." SHOULD BE "The hunt WILL BE good today." (The response to this line indicates that hunting has not commenced yet: Nagrub: "Yes, mother. I'm eager to prove my skills today."
DialogueNarzulburMulGadba3: Speakers should be reversed, for the same reason as above ("Can we both be chiefs?" sounds like one of those dumb questions Gadba would be asking.)
If you want to use it, I would be honored

. Also, if you do fix these same things, any updates I make to my mod will only include updates, so when the USP comes out, I won't be redundant. I'll just refer people to you!

THANK FOR ALL YOUR HARD WORK!!!!!!!
Edit: ATM, I am learning scripting so I can stop that daggum giant attacking after The Cursed Tribe is completed. But I am a not-quite-complete-scripting-newb (I know a LITTLE about scripts!), so it may take a few days.....
