Yes, that is correct.

I think you are about right.

This is the approach pretty much all Linux distributions
follow, because by building everything from source yourself,
you can ensure that you are in possession of all the pieces
used to create the binaries & thus be able to distribute
them for license compliance. If in doubt, I'd go for this
approach of building everything from scratch.
