Dear Karimabder
First of all, welcome to the David Allen/GTD board.
Second of all, I'd like to reassure you that there are quite a few people here, who have tried different "models of reality" for Life Management. I'm sure with that much pooled experience, you will find either some direct resolutions to your questions, or at least be steered toward appropriate tools for your needs.
Third of all, as a (relative) newcomer to the boards, you're not going to emotionally move any of those people to work with you by critically evaluating how many replies you've received to how many people have viewed your post. Be patient, and try to keep it all in perspective. There may be people who have viewed your post who have not yet achieved your level of organization, so they may be learning from you, instead of you learning from them.
All that being said - it sounds like your organizational skills are fine; but the missing piece of the puzzle is moving data & knowledge to action and results. Most of David's material is "bottom up" and it sounds like you are fine at that level. You may consider a "top down" approach to link your actions to your outcomes, and understand why you want them in the first place.
For that - I might recommend either Hyrum Smith or Tony Robbins' "OPA/RPM System." Robbins has built his reputation by being a motivator, and once you get past the infomercial image, you will find some highly valuable tools in his "OPA/RPM" materials.
I'll leave you with a thought from Dan Millman, that "the path" unfolds beneath each warrior's feet differently.
Continued Success 8)
