Follow-up about progress, I think there are two ways to handle this:
Is there a reasonable way you could describe one goblin setting up another? If so, then that's what progress is. They improve position but someone else needs to address the problem (good idea or roll).
Instead, I tend to take all-or-nothing rolls like this as good context to shift positioning down to Bad (unless they are really well-prepared for it). In a bad position, actions are binary (1-4 is failure, 5-6 is success) so you don't have to worry about what 'progress' would look like.
