Hi Andres, You probably just have to install GRASS [1] and SAGA [2] because those aren't included with QGIS. They are entirely separate software packages =)
Then you will probably have to configure the processing toolbox [3] so that the GRASS and SAGA tools can be used. Those can be found in the "providers" portion. Another option is OSGeo4W [4] which provides an installer that will get all or any of the above for you (qgis, saga, grass, etc...).
