Are there other time organizing or self organising techniques or books/theories/articles would you recommend after pomodoro technique ?
There are tons and tons of what you're asking for! Since the question is rather vague I will list some resources that I either have found useful myself or that are generally widely popular.
I think Getting Things Done (GTD) by David Allen is worth mentioning due to it being a highly acclaimed method among people who seek to improve their productivity. By getting your tasks out of your mind and into your task management system (which is explained in detail in the book) the GTD method simply helps you get those tasks done once and for all.
There also exist several task management web apps aimed at implementing the GTD method. One I can recommend is Nirvana, but the "best" way of implementing GTD is an evergoing discussion among GTD enthusiasts.
Highly popular blog about personal productivity and other topics in personal development. One of the better free resources I have come across. Don't be surprised if you find yourself hopping from post to post in search of helpful productivity tips that might work for you.
Like many other I think one of Pavlina's most interesting posts is about getting up early, which in itself has some immediate implications to productivity.
This self-help book by Neil Fiore is another acclaimed title. Personally I like it because it appeals well to procrastinators and goes a bit further than the "just do it"-advice (which is hardly useful) often given in other books of the same kind. Fiore's approach is based on identifying the root causes of procrastination habits and how to effectively deal with them. This is contrary to commonly offered advice of the type "procrastination can be overcome by not procrastinating".
The book is also worth checking out because of Fiore's "Unschedule" -- a time-management technique based on scheduling only your activities outside of work (aka "guilt-free play"). Getting actual work done comes after you have made your Unschedule and realized the limited time you actually have at disposal.
This is a useful tool if you do a lot of work on your computer and are facing problems with distractions. It is well known that in order to improve productivity it is essential to know where to improve and the only way to know this is if you track your activities. Problem for many of us is this area is that we can't be bother to consistently log our activites during the day. RescueTime automatically (and it is really good at it) tracks which applications and websites you are using both offline and online and you can find detailed stats in a neat web interface.
In the answers to just about any question here on Productivity you will find links to other useful resources for increasing productivity.
I was searching for this blog post when I first wrote this answer, but I couldn't find it at the time. I believe it is worth a read as a word of caution before getting lost in the vast amount of self-help books and articles available.
7 habits is a well-known method for life organization.
Pay attention to all senses for distractions - sounds (the most obvious), but also visual, e.g. high traffic area, smells and physical environment issues such as heat and cold.
Pay attention to the physical layout around you and make sure it is well organized and easy to find things.
Always replace items to their "place" or leave the "out" temporarily.
Use an electronic calendar and try to schedule as much as you are comfortable with.
Use to-do lists for minor tasks and tasks with multiple steps.
Schedule quarterly clean-out of items so that for the rest of the time you can focus on your tasks.
