You only need consent if any of the previous contributions did not
have a "or (at your option) any later version" notice.

It is completely up to you, but I would certainly support the change
to GPLv3+. Make sure you keep the "or later" part though (ready for
GPLv4), and update the address information to be the URL as per the
recommended GPLv3 style.

This would be an example header if you decide to do this:
