My personal plan at this point is to use StoreLaw. The program already has built-in commercial outlines keyed to various texts, and I plan on adding my own notes to the outline already there. I think that having a "skeleton" will help me in the beginning, since I also have not a clue as to how to get started. I know that I MUST have some order in my material or I get frustrated.
Just so you know, the "outlines" that you can download from StoreLaw are just the casebook's table of contents in electronic form. There is no substantive material in them.
