If the project becomes too much for you at any point, remember that writing an autobiography takes time. Take the pressure off. Relax. This is your autobiography. You can make it as brief or as complete as you like, but don't expect to write it quickly. It may take years. If you want to finish fast, you might try the $14.95 Memorygrabber software I mentioned early. The publisher offers numerous free downloadable pages on their website, so you can decide if that approach will be useful or not.
Online publishing has an advantage of extensive reach. There are no restrictions on territory so your book can be purchased and read in any part of the world. Research online publishers, submit your query letter, edit the copy, wait for approval and have your work published online – it is one of the best feelings you could possibly have to see yourself on a virtual shelf in Amazon and a dozen other online bookstores. This is a great course on publishing.
