How to install GnoMenu theme?
I wrote the full process at this post "Alternative menu for Ubuntu GnoMenu". I am telling here in short.
Most of these GnoMenu theme comes in a .tar.gz file. Click on 'install' button on GnoMenu options Themes tab, browse to that .tar.gz file and click OK.I don't know whether these are best or better GnoMenu theme or not. If you feel these themes quite nice, useful or feature rich then other, then my choice will get a success.
If you get any theme comes in a zip archive, then extract it. You should get a .tar.gz archive.
