Hi cgdvs,
Particles don't have a mapping color, just mapping coordinates, which can later be read by the viewport/render to assign a material. You can sample colors from a texmap using a script operator, but not currently any other way.
All the other requests can easily be achieved using a script operator.
Attached is an example scene showing how to sample the nearest normal/color on a surface and use those values to set particle positions and outward velocity.
Once you get more familiar with scripting, you can enable multithreaded scripting capabilities which will greatly increase the speed of doing operations like this with a Script operator.
