Having said that, I'll take a swing at these:

Normally it's specifically labeled, but yes.

Early in the process, like before the build is started. All of the build sheets and manifests are printed and distributed a day or so before the build starts.
Just to be clear: to me "serial number" = "sequential portion of VIN"

I think you are saying that is 100% safe to assume that sequence numbers in between those two were built on 11/12/71.

Sequence number = Yes. By definition. Because even if you have re-ordered the VIN/Serial numbers the new build sequence numbers are still going to count up one by one

Yes. Although in this case it is the VIN/serial number that exists and is assigned a new sequence number (not the other way round).

Depends on the plant (because of the accumulators and buffers, and lack thereof).
Fremont - 99%
Flint - 60-80%

Firewall - yes. Any place where components were assembled off line and conveyed in sequence to the main line: Front end sheetmetal, radiator support, grille, axles, tire/wheels, seats, etc. But - it will typically be the last two or three digits of the sequence number, in a form of shorthand. Not the full six digits of the full sequence number.
SPID - no. The sequence number does not appear on the SPID
