That should be emerge ... @system and when you get that done, then do
emerge ... @world.  Sometimes that helps, sometimes not.  When stuck,
it's worth a try.

Almost all the time, the news item tells you if you need to do something
and what to do.  If not, it usually contains a link that explains what
is going on and what to do.  Some, maybe most, are also targeted in a
way that they only display IF they affect your system.  Example. 
Something only affects KDE and you don't have anything KDE installed. 
It won't display since it doesn't affect you.  If you do have KDE or
part of KDE installed, then it shows up.

I use eix-test-obsolete to find most of those.  Keep in mind, there may
be times when it says something is redundant when it isn't.  Example.  I
run unstable KDE here.  I have all of KDE listed in package.keyword. 
However, if all of KDE that is installed is stable, it says it is
redundant and can be removed.  However, a week or so later, I'll need
them again when the next unstable release hits the tree.  One has to
think about what goes and what stays.
