Help - SOLIDWORKS Tutorials.
Work through all of those a few times, and you'll have a decent understanding of the software.
That said, SOLIDWORKS is not really meant for creating 2D drawings. It can, but you would ideally create a 3D model of the object first, and then generate the 2D drawings from the 3D model.
