First of all I would like to say that Umer has left no stone unturned in guiding you properly and comprehenisvely. One thing that I want to clarify is, only social problems are written in the form of Issues, Causes, Effects and Remedies. These you usually cause and effects essay where different approach is practiced. The topic you have choosen is argumentative essay where you have to win the battle with your arguments and logical support. While saying issues we simply mean the concepts and ideas associated to that particular problem that is prevalent in the society.

Now lets move to your questions one by one.

For collecting relevant material you have to search out the importance / significance of dialogue for dealing issues. Some relevant examples from near past to support your arguments.

For arrangement definately you have to draw an outline and then arrange the material accordingly.

If you want to give your original expression do write in your own words. First read as much as possible relevant to your topic and then rephrase yourself.

Here I am reproducing an outline that I had rephrased from original outline of Saleeqa at a following link:

I hope this outline will help you to shape up your essay.
