Read the articles "Understanding Stability" and "Understanding Trim" to get a foundational understanding of how to use many of these templates.  This article describes fundamental concepts that must be grasped for doing effective stability calculations.  It cover's the vessel's weight contribution, the vessel's shape (hydrostatic) contribution and how to tie these two sets of input together for determining transverse stability.  The article is for transverse stability but the concepts do carry over into longitudinal stability.

Another method to learn about stability is to study simple barge stability and then progress to more complex boat an ship shapes.  See the article entitled "Quick Barge Trim, List and GM (Initial Stability) Calculations."

The parallel axis theorem is important both to structures and stability.  There is an article entitled "The Parallel Axis Theorem."

The following are some general references that are recommended for background preparation.
