"Is there really any requirement for the commerce being manufactured (putting aside the obvious problems with the idea of "manufacturing commerce") to actually be shipped interstate for Congress to assume authority to regulate it?"

Requirement? It's the definition.

Congress does not have the power, under the Commerce Clause, to regulate commerce unless it's "among the several states".

Can you give me a specific example of something that isn't "among the several states"? There seems to be some discrepancy between Congress regulating something as "commerce among the several states", and it actually being bought or sold across state lines.
