Can someoe tell me if they are any free software I can download? like blender etc and software that will help me make uv maps and modelling because I haven`t a clue where to find it.

Google is your friend >>> https://www.blender.org/

Then start looking for tutorials.  A nice place to start if you want language that is relevant to SL is http://blog.machinimatrix.org/category/mesh/ , but there are hundreds of other tutorials on line.
