Citation Issues

I have 6 letters from the 1920s-1930s that I am going to cite.  These are on business letterhead and are letters of recomendation not addressed to anyone in particular. My grandfather worked as a cooper.  The letters from his employers stated he did good work but had to be let go because there wasn't enough work for him to do. He worked for periods of time then on to the next employer.  He worked for one of the employers 4 different times.

I've searched the forums, but I couldn't find a post that I thought answered my situation.

I'm starting to work on my own genealogy, with myself. I have in my possession the original marriage certificate that was issued when I was married. The certificate was issued by the county clerk's office.

The top of the document states "Certificate of Marriage". The bottom of the document states "LICENSE ISSUED BY THE CLERK OF _______COUNTY____________19______" blanks filled in with the date the document was issued.

I'm wondering how to properly write a reference note for "Torrey's New England Marriages to 1700," a collection offered online by the New England Historic Genealogical Society (NEHGS) on their American Ancestors website. This is the online version of a book published by NEHGS in 2011, and is a transcription of Clarence Almon Torrey’s 12-volume manuscript. A print version came out in 1985 (minus the references) and then NEHGS produced a CD-ROM version in 2001. The 2011 online version is derived from the CD-ROM version. 

Dear Editor;

I have a minor question that developed as I reviewed the Evidence Explained (EE) book.

When constructing a citaton, using QuickCheck Models, there is a field called, "WEBSITE TITLE". The example content of this field is often shown as, "Ancestry.com". I believe the ".com" denotes the American site. There is also a Canadian site, "Ancestry.ca" and even an, "Ancestry Library Edition".

I read over the sections of Evidence Explasined that relate to Online Database Entries (Canadian Archives). I am having a little problem understanding the functionality of each of the segments of the "First Reference".

I am struggling with how to cite a Death Record from a Coroner's Register using Legacy.  I found the record on Family Search, so I could use the template for Internet > Database & Images.  The records  were created by the San Franciso Office of the Medical Examiner and are held by the San Francisco Public Library, San Franciso History Center.  The library catalog says, "The collection is available for use during San Francisco History Center hours, with photographs available during Photo Desk hours.

I need some help with citing a particular document. I downloaded some digitized images from TNA (UK) and now I'm really confused how to cite them. The exact item I downloaded can be found here: http://discovery.nationalarchives.gov.uk/details/r/C1733893

This may appear to be a super dumb question, but I am going to ask it anyway. It may not even belong in the EE forums, so I apologise in advance if it is not relevant.

I am just wondering what others do for the given name and any other name varients of their ancestor. Do you give a source/citation for their name with every given instance of a record that you may have found?

I'm not confident the best way to deal with archaic letters, spelling or language.  For example, here's a citation where I've quoted an entire entry:

Normally when you cite an email you put [(E-ADRESS FOR PRIVATE USE),] but if the email is from an official of some sort (in this case the clerk of the circuit court) can you go ahead and put the actual email address?  It seems a bit odd to privatize the email address of a govenment official.
