Questions that pop into my head by reading your posts are:
1. What kind of printing are you planning on doing: offset or large format inkjet?
2. Why would you need to use pantone colors to recreate these no matter what printing method your using?
Pantones are a reference guide used to accurately reproduce colors. Companies with corporate logo guidelines will refer to Pantone #'s in their logos etc to ensure colors are consistently reproduced.
This doesn't mean you always have to use them. I don't know what the symbols are that you're referring to, but I would be surprised if matching pantones would be required.
Agree with the previous statement.
You probably need to give us more information on what you're trying to do so we can help you properly.
