As that just downloads metadata (IIRC) - nothing.
Yum does this automatically without you asking if the local metadata is
'old' (you get to choose the age involved)
If you want to force the issue,
yum clean metadata
will clear the cache first, so that it gets refreshed on your next yum
command.

well, the closest I can think of is yum --skip-broken
yum update --skip-broken
will update everything for which it can resolve all required
dependencies and skip the rest.
There may be other yum plugins that add this sort of functionality
yum update
will attempt to update everything it can on your system to the latest
versions in the repositories. This sometimes fails if a dependency is
missing (usually down to someone not packaging something correctly, or
the mirrors not having completely synced yet).
That's why --skip-broken exists.

That we don't have, exactly.
Although there have been tools on Fedora to do distro upgrades
(preupgrade, for example.)

man yum.conf
(man -k yum for those who like to find this stuff themselves)
It has a 'repositories' section, with examples.
but, as it is basically very simple:
[reponame]
name=human-readable name
baseurl=
http://.../
Plus other options if you really want them (like enabled=0|1,
gpgcheck=0|1, gpgkey=/path/to/public.key...)

** this would be the sources.list file that totally confused me when I
first got to it? Never mind all the apt pinning stuff... :)
