Help with custom Grub2 menu

[Richard Owlett]

I have a machine set aside for experimenting with OS 
installs/configuration.

I'm currently experimenting with Debian Squeeze and Wheezy.
Debian's installer defaults to
  1. making the last install the default when booting - can be 
bad idea if
     you mess up the installation. I want the first OS installed 
to be loaded
     by default.
  2. creating menu title from id of installed kernel. As 
multiple installs may
     use the same kernel, I wish to use meaningful label.

Is there a tool &/or documentation to make life simpler?

TIA
