I'd say that your issue doesn't need a organizational solution, it's a deeper question.
I go by "when why gets bigger, how gets easier".
I would suggest sitting down and writing out 100 (or however many) reasons for what you are trying to accomplish. As you have those done, your motivation will grow and get you past the little distractions. The more reasons you have for accomplishing your goals, the easier it will be to get desciplined.
That's also been my experience. There is a really good book that can help you get a handle on why precisely you procrastinate: "Procrastination: Why You Do It, What to Do About It" by Jane Burka and Lenora Yuen. It was published in 1983, but I still haven't seen a better one on the psychology of why people procrastinate.
EDIT: The problem is big and complex enough to need a book to cover it. Blog posts and magazine articles usually only cover a specific, narrow aspect of the problem. This book as well as covering the field is readable enough that it doesn't take too long to read through.
They have recently come out with an updated edition (2008). It still covers a lot of the same ground but has been updated with current research in neuroscience. I would also say this isn't a book that you read once, but rather is something to refer to/re-read again and again as you are working through your procrastination.
