I just wanted to recommend two complementary books on procrastination that REALLY helped me:
The Now Habit, about the emotional side of the problem. I found this book really great.
Getting Things Done, on the more practical, organizational side of the problem.
Another one, less directly related but useful, is
The Power of Less, about how to concentrate on what's really important for you.
Also, be persistent. Procrastination is a deep, multi-layered phenomenon. It takes time to understand the emotional reasons behind it and also quite a bit to set your information in a way that works best for you.
I have been working on it for many years now. It's been well worth the investment, but it does take time.
Good luck!
