You have urpmi. Change to root to use it. If your system has sources set up already, they will be listed in a file in /etc/urpmi/
To update the lists 'urpmi.update -a'
To install a_program 'urpmi a_program'
It does pattern matching, so you can do things like 'urpmi firefox' and it will either install it or tell you the options. It does dep. checking too.
Here is the place to go:

There you will find the commands to update your sources the was you want.
