1. Roland still "fans the trigger". That's not how a gun works. You fan the hammer.
2. The artwork for the gathering in the compound after the attack on the guards which shows the Ka'tet together appears in the book after Eddie is shot. It should be immediately after they gather.
3. Whelan's drawing at the end of the chapter after Ediie is shot shows Eddie with his hand over his LEFT eyebrow. The book says the gunshot entered over Eddie's right eye.
