Hi,
I don't get what you mean by "raster layer component"...

However for anything related to rasters start with QgsRasterLayer
class and friends (all the raster-related classes are in qgis sources
directory src/core/raster).

You can't do anything with QgsLegend since it's not a part of QGIS
libraries (it's quite tightly bound to QGIS application itself).

Where to start when trying PyQGIS:
