I know how Blender's user interface seems difficult at first. Of course it's up to you to decide what to do and how to do it.
But my really advice would be to use Blender as a simple front-end to a free renderer (YafRay for example) so you'll don't have 3D modeling to do in it, only defining shaders and lights and setting up render. And start rendering, of course
If you want to look further in this way, feel free to ask any Blender-specific question.
