I get asked many questions about how to publish and what options are available and so to answer the most basic questions, I've uploaded a book to Kindle A Quick Guide Through the Publishing Maze. It has an overview of the different publishing options, basic formatting instructions for self publishing on Kindle and with Createspace and some tips for choosing a print on demand publisher.
I'll be updating this as I get more questions, so feel free to let me know of any additions you would like added.
If you don't have a Kindle, you can use Kindle for PC to view books.
