When using Dr xxxx, the PHD may or may not be used in speaking, in a situation where medical doctors and PHD's would make it unclear the PHD should be used the first time. In written form the Phd is proper when the Dr is used. Mrs does not normally have the Phd appended.

Yes, individuals who have earned a PhD degree can go by the title "Dr."
The appropriate salutation for a business letter to Dr. Ben Corliss would be "Dear Dr. Corliss." It is essential to use the appropriate title and last name when addressing a professional in a business setting. This salutation shows respect and acknowledges Dr. Corliss's professional title.
I have never seen Dr after a name. It may be MD, PhD, EdD, DDS, etc. depending on your field of study. Still, if the degree is a doctorate, the Dr would go before the name. Thus as an example, John Smith PhD, or Dr. John Smith.
Dr Josef Mengele was awarded his PhD in anthropology in 1935 from the University of Munich. In 1938 he was awarded his PhD in medicine from the University of Frankfurt.
I think it's preferable to go with "James R. Jones, PhD," although you could also say "Dr. James R. Jones." Please never use both "Dr." and "PhD" at the same time...pick one or the other. The saluation of the letter would then be "Dear Dr. Jones," and so on.
Ph.D comes after the name. For example, John Doe, Ph.D.
Before the body
Right above the salutation.
The salutation itself ("Dear Ms. Jones") should not include your return address. On a business letter, the return address can go in the upper right corner of the cover letter. The salutation goes below the delivery address.
