I made one important omission in Part I of the Getting Started with the Web Services SDK series that a colleague brought to my attention (thanks for the reminder Ty!): I didn't include BusinessObjects Edge as one of the products that includes the WS SDK.
I've updated Part I to include this now and I also updated some of the formatting of the article.
I updated the introduction to include an outline of the article (similar to a table of contents so to speak), where you can click on the name of each section for navigation instead of having to scroll through the article and also fixed some of the formatting with the bulleted lists.
