Here is a great tutorial for creating business cards using Inkscape. This tutorial has two main sections.
The first details how to create a printer ready template from a PDF guide using clones and guides. Using clones in this fashion to create a template in inkscape is awesome; once the template is created correctly, the changes that are made to the original populate thoughout the rest of the tempate!
The second section provides a detailed process for creating a basic business card (with a nifty pinstripe background). This portion of the tutorial is a great introduction into basic fill / stroke techniques, pattern fills and text editing and kerning.
