Trygve, you seem to be suffering from information overload. Otherwise known as "paralysis by analysis".
Pick a plan and stick with it for a few weeks. When you've given it a fair trial, evaluate and change something if it hasn't been working. Or better yet, find a smart trainer to tell you what to do. Let someone else stress the details, while you put the plan to work and watch what happens. It's a good way to start learning... better than reading till your eyes are spinning in opposite directions.
