Three Pre-searing Questions I Haven't Seen

I've read through the first 13 pages of threads and didn't see these answered, so if someone could please post:

1) Where is the vault in Pre-Searing?
2) Is it possible to hire a henchman in Pre-Searing?
3) Are bandits the only mobs that drop dyes, or are there others that drop more frequently?

Just want to be sure I know how to do everything possible before I go to Academy, 6.5 now and going in when I hit 7. Thanks loads NONE
