Yes. "split user" means that /bin and /usr/bin are two different
directories.  Likewise for /lib and /usr/lib, and so on...

It doesn't matter that /foo and /usr/foo directories are in the same
filesystem.

Yes.  And depclean.

Yes -- If you're using OpenRC. I assume you are not using systemd
since your old profile wasn't a systemd profile [In theory you could
be running systemd on a non-systemd profile, but it's not common.]  If
you are running systemd, you should first update to the "merged-usr"
flavor of your current profile.

There's a detailed table at

  https://wiki.gentoo.org/wiki/Project:Toolchain/23.0_update_table

It shows exactly what new profile corresponds to what old profile.

Yes:  https://wiki.gentoo.org/wiki/Merge-usr
