Question

What information is important to include in an About dialog?

Definitely:

• Name of the software
• Version
• Copyright notice

Usually:

• Assemblies versions (for .NET applications)

Answer 1

Bare minimum would be version number, build date (and time), copyright, a way to get at the text of the EULA, creators (either individuals or company), and libraries used.
