If you are really unexperienced, I would suggest to use Blender dry for quite a while. This is a professional program and it is complex and challenging enough. If I could recommend first downloads, then I would say: tutorials, tutorials and tutorials, nicely gathered in a folder.
Ok maybe i exagerated on the innexperience. I guess i say that when i look at what some people achieve with blender. I been playing with blender for about a year now!
Go there http://www.download.blender.pl/mirror/
at the very least pick up the texture and material plug-ins and have a good look or better at the documentation.
