That's quite easy:
1) lookup the string value
$version = HKLM_LOCAL_MACHINE\Software\Novell\Mono\DefaultCLR
2) lookup the string value
3) (optional) detect whether $mono-prefix\bin\mono.exe exists.
If one of the steps above failed, Mono is not properly
installed or too old.

Usually the tool (1) which generates the MSI is able to create
icons almost automagically.
The shortcut target is
The shortcut's command line
The shortcut's icon
(1) I can't really recommend one, but have a look at WiX:
Despite of its very misleading name (for Germans ;-),
it's a nice toolkit.

This can't be provided, because this would require that
MS.NET is installed on the machine. Otherwise the MSI engine
won't be able to execute the custom actions implemented
by your assemblies.
