The others are the names of the repositories they were found on. Look
under /etc/yum.repos.d/.
It doesn't matter much.

"man yum" is worth studying carefully, it has lots of gems in it.

BTW - I'm not sure that "apt-cache search" is the same as "yum list |
grep" - apt-cache search looks for multiple keywords in the
description as well (unless you do "apt-cache -n ..."), "yum list"
just lists package names. You can use "yum whatprovides" to search for
files (a bit like apt-file).

It's Centos (Community ENTerprise OS). And you should check rpmforge
and EPEL for anything you can't find on "vanilla" centos.

BTW - I see an icecast package for CentOS in the EPEL repository:

# yum info icecast
Loaded plugins: fastestmirror, priorities, security
