"all points of activation" -- all non-zero vertices? This is likely to be a lot of vertices.
More often one is interested in the center of gravity of a supra-threshold cluster, but let me answer your original question. You could save the coord, metric, and paint file as ASCII and strip the header off. Then use a third-party software package like Access to join the three files by vertex number. You would need a preprocessing step on the paint file to convert paint indices like 1, 2, 3 … to area names (this lookup is included right after the EndHeader tag in the paint file). But if you're really just interested in the centers of a few hotspots, the easier thing is to look at them in Caret; click on the center; and read the paint name and metric value out on the ID window, along with the x,y,z.
