Create a Location object for your calculated centroid, then use the Location's
FindNearby method to find "places of interest" nearby.
I haven't tried it, but I think you can select the type of place according to what is currently displayed.
Automatically identifying the contacts for each cluster is a bit more involved. A brute force search/comparison is NP-complete of course (takes a long time). There are some cluster analysis algorithms around though - you might find something by Googling. I found some Fortran code to do it, but haven't got around to trying to get it to work yet.
