Exactly (supposed your ARCH is amd64). This is usually what you want,
because security issues are usually not fixed (and sometimes not even
reported) for ~ARCH versions, i.e. *if* you run an ~ARCH version, better
use the highest one.

Yes. And when this happens, you should remove the "**" unless you want
to continue to install the newest bleeding edge gcc. (This is why
eix-test-obsolete informs about it - of course, only if you run it
after eix-sync and *before* emerge -NDu world).
