I am mostly of the same conclusions as you Flying Squirrel, but I would add,or respond with a few thoughts:
The individual National forests seem to each have their own way of writing the rules about this subject, but from what I can tell they all seem to have about the same policy, which I imagine is more or less so.
Point 1: I think taking movie for personal use is allowed without a permit, at least the Umatilla NF says: "If you are shooting still photographs or ‘home movies' for personal use (i.e. that does not involve advertisement of a product or service, the creation of a product for sale) then a special use permit is not required."
2: To comment on what is considered a prop, or set, I don't think "set" refers to the set-up you use to take the pictures with "Still photography uses photographic equipment to capture still images on film, digital format, and other similar technologies. National Forest visitors and professional or amateur photographers do not need a special use permit to take still photographs unless the still photography will:"...
From Umatilla again.
3: As I mentioned before, according to this page
http://www.fs.usda.gov/detail/chugac...TELPRDB5199833 not all fees would necessarily be 1000, or 1500 dollars.
My vote would be for the less hassle for us photographers under reasonable circumstances, of course, now and in the future.
