I just figured it out. I knew I somehow had to use Style. But by beginning with EdgeLabel instead of VertexNumber, I was misled into thinking it would not work. Here's a simple example: ShowGraph[Cycle[3], VertexLabel -> (Style[#, FontSize -> 20, FontColor -> Green] &) /@ {"1", "2", "3"}, EdgeLabel -> (Style[#, FontSize -> 20, FontColor -> Red, FontSlant -> "Italic"] &) /@ {"a", "b", "c"}] The documentation about the graph functions in Combinatorica (and the rest of the package?) is really terse to the point of being nearly nonexistent. And it's unclear that the Pemmaraju & Skiena book "Computational Discrete Mathematics: Combinatorics and Graph Theorey with Mathemtica", written for use with the "new" version of the Mathematica 5.2 standard add-on package DiscreteMath`Combinatorica` is much more adequate or completely compatible with the Mathematica 6 implementation of the package.
