A copy of GUIDE TO MISSOURI CONFEDERATE UNITS, by James E. McGhee might be helpful. The following link will take you to american civil war.com where the book is available for sale:

Just a suggestion--I have no stake in the sale of Mr. McGhee's book. Will be following this thread and hoping to learn something myself.
Best regards, and good luck.
