Most of the tools you mention are very good tools, but the hard part of learning to get things done is acquiring the habits. A good example is the clear separation between next actions you want or need to do, and things you might do, which might go in project support materials or on a someday/maybe list. Other examples are distinguishing next actions from projects, or having clear outcomes. I think you should consider investing in the gtd implementation guide, which is really systematic. I am not good with paper, but many people have found that it works well, particularly as a starting point. I have used many of the list tools you mention, and most are fine for gtd. Things and iCal work well, for example. I would be careful using Evernote: one must carefully separate actionable items from reference.
