The layout itself is just a list of coordinates, so the labels are not 
available, but you can make use of the fact that the coordinates in the layout 
are in the same order as the vertices in the graph, so you can do this:

from itertools import izip
for name, (x, y) in izip(graph.vs["label"], layout):
    print "%s\t%f\t%f" % (name, x, y)
