ADS-B is leading to Free Flight ... so here few questions:
Time-line of global implementations;
Basic principal and very basic theory of operations.
1. don't have any idea.
2.what I read somewhere, it uses the GPS, then it transmitting (broadcast)the information (flight ID, direction of flight, speed,etc) to other traffic and some ground base station as well.
I imagine this would be a radar_like display for pilot.

1- mostly used as I know in the orient for high altitude reporting... Will be a slow implementation into congested functions.
2- take another responsibility/liability from the pilot/airline. As is now it reduces problems due to language communications, one day i see it recieved by fms and commanding flight environment changes.
V1... Ooops

Here is a link to a quite comprehensive explanation (in reasonably simple terms) at Wikipedia (http://en.wikipedia.org/wiki/Automatic_dependent_surveillance-broadcast). It's not a scholarly or technical article, but I think it will provide the information you are seeking.
Both of your questions (what is it, and what is the timeline) are answered in the Wikipedia article.
