This was my big "ah-ha" moment when I listened to the David Co. Projects audio CD set.

A project list is just a simple list of each successful outcome - the tops of the file folders as David calls them. At least one next action is just a description of the next physical, visible action.

So where does all the other stuff go? Project support!

There's a temptation to make the projects and next actions lists do more than intended and part of the reason is project support gets undersold in describing GTD.

A lot of the time I START in project support by using a sheet of paper and dumping everything I can think of about the outcome. The I distribute the outcome and action to those lists. Then if I want to add content or do brainstorming I go back to project support.

It's really simple but big payoff.
