If I understand what you are trying to do, I think the easiest way to 
show labels for some verticies and not others is to conditional set 
either the vertex label size (label.cex parameter) to zero or the 
vertex.label to blank "" for the labels you want to hide using the 
ifelse function.


bet<-betweenness(gn)
gplot(gn, label.cex=ifelse(bet>0.5,bet,0) label.col=1, 
label=network.vertex.names(gn), vertex.col=2, edge.col=8, vertex.cex=0.5)

or


bet<-betweenness(gn)
gplot(gn, label.cex=node.scale(node.scale(bet)), label.col=1, 
label=iflse(bet>0.5,network.vertex.names(gn),""), vertex.col=2, 
edge.col=8, vertex.cex=0.5)
