Who is "we"?
And secondly, for all legal questions, please consult a lawyer for your
company, they are the best to answer these questions, not random
developers on a public mailing list.
And no, the GPL does not say you have to add a changelog to the license
header.

No, no need to change the author, just know about the copyrights of the
other companies and authors and deal with it properly as per copyright
law.

What did you change? Why not just post your change as a patch and get
it accepted upstream properly for everyone to then use?
Please read the kernel files, Documentation/SubmittingPatches and
Documentation/development-model/ for how kernel development works.

Yes of course, you can not change the license of the file, or the Linux
kernel, why would you think otherwise?

That is up to you.

Where did you look, there is lots of public information out there.
But again, you should always ask lawyers about legal things, not
programmers.
Hope this helps,
