I hacked together a few changes...and came up with a script based on jhncbrwn's OF "Task to Email" script and the original "Complete and Await Reply" script by Curt Clifton that jhncbrwn mentioned.

I changed a few of the text notifications to suit my need, and depending on how you look at it added a feature to the scripts:
-I either added email notification to Curt's script...or
-added Growl notification to jhncbrwn's script.

I'm still interested in seeing if a link-back to the email sent can be added to the notes field of the waiting-for action that is generated. I've been unable to cobble one together...but my scripting skills are purely plagiaristic.

Here is my version of the script...based on Curt Clifton's and jhncbrwn's scripts:
