Some additional information:
YaST is the control center for the SUSE system configuration. Whenever you would like to adjust, install, update, add or remove something, have a look at YaST first.
A submodule of YaST will run updates. It is called YaST Online Update, often refered to as YOU. It helps you to install updates and bugfixes of previously installed packages. If you would like to install new packages, see Jongi's post.
You can also use APT if you are more familiar with that. There are more and mor repositories for SUSE APT. http://linux01.gwdg.de/apt4rpm/
