Part of the problem might just be that it will take some time for you to trust your system. I've been using GTD for a little over a year now, and at first my brain had trouble letting things go. After a while, though, I started to figure out that I really could forget something, and because an appropriate reminder was in my system, I could move on to something else.
It might just be a matter of forcing yourself beyond gut-level behavior. In the example above, try forcing yourself to move out a project mindset, and just keep moving through your list.
One other thing that I noticed - you said that after moving a note about email to your @Waiting For list, you added 3 or 4 or 5 NAs to your list. This might be too much - try just adding one at a time. I have a lot of projects with concurrent NAs (meaning that there are several actions that can be completed now, without waiting for another task to be completed). Still, I'm very careful about how many NAs I add to the list, because otherwise I get overwhelmed.
I think you're on the right track - it just might take time to get used to this different way of thinking and doing. Stick with it.
