We just did this thread back in July.
Here's a summary of 3 techniques, adjusted for Growl:
tell application "Finder"
{exists file "Growl.prefPane" of folder "PreferencePanes" of folder "Library" of startup disk, ¬
exists application file id "GRRR", ¬
exists application file id "com.Growl.GrowlHelperApp"}
end tell
The Finder can't see into the Growl.prefPane package to check if the helper is there, but I would expect the prefPane to be sufficient. The other two are better though, since they check specifically for the helper in a path-free machine independent manner.
