Thanks again for your help... I am a bit meticulous (OCD if you will); therefore, it comforts me to have as much as possible where it is supposed to be, and doing what it should:
With that in mind... I went through many applications/extensions/etc. to sort them out. I figured out that my method (Editing file types), is a way to creat short-cuts as you described (i.e. by right-clicking... Bolding the words "Open/Play/Etc."). Also, these are short cuts for any extension (type) that you want... which will also specify which application is used to do what you want; and belive me... I went through a lot... lol.
But to sum up the indiscretion of changing the program for opening audio files; it was as simple as right-clicking on the D drive (as you stated), clicking on the Auto Play tab, and then picking from the options (Media Files, Audio CD files, Video files, etc.). On the Audio CD drop-down, the answer was "Show files with iTunes." Therefore, when I now insert a CD, iTunes opens but does not play the cd; also, I specified in iTunes (probably pointless as I did it in the D drive) to ask for import (which it only does if iTunes is already open before inserting the Audio CD).
It was as simple as that... my process did teach me a lot about extensions/file types, but essentially was only a way to narrow down the exactness of an Audio CD (i.e. which program opens MP3 files, MP4 files, etc.).
*ALSO, to answer your question about right-clicking a file type: it seemed as if this setting was only saved for that individual file, not for every one of the same extension. Therefore, by editing the file extensions I was able to keep file types grouped and thus the settings as well. In addition, the only harm with deleting an extension/action is that if a file needed to use that extension/action, it will state that the type is not specified and prompts the user to look for a way to open the file (as most people have probably seen before).
I appreciate your patience and help with my confusions. Thanks a bunch...
