You can do 1) with the new Combinatorica package which comes with Mathematica 4.2. Or you can download the pre-alpha version of the package which is still available at: http://www.cs.uiowa.edu/~sriram/Combinatorica/NewCombinatorica.m 2. The best way is to do this "by hand". There is a Java based graph editor, both for the new and old version s of Combinatorica, check the link above. 3. Again see the above link.
