Citation Issues

I am a couple of weeks old in experience with Evidence Explained, so please bear with me on this. I’m sort of feeling like a ditz here.

As an example, I want to use the following source: https://familysearch.org/pal:/MM9.1.1/VC19-8GQ

In this one record, I have:

1.       The marriage date for Johann Heinrich Metzler and Anna Katharina Seibert

2.       The location of their marriage.

3.       The birth date for Johann Heinrich Metzler.

4.       The birth date for Anna Katharina Seibert.

What's the consensus regarding citation of a prior work by ones self? For instance, if you have previously made a particular case, or a reasoned argument, and you wish to make reference to it in a new work.

In scientific and mathematical works, there would be no difference, but I wanted to confirm this in the specific realm of genealogy and historical research because the subjectiveness of an authored work rates less highly than more objective sources, and for fear it sounds like the I-disease.

I’m in the process of cleaning up 30+ years of research. 

My current problem stems from not always documenting when I accessed records.  However, I have hundreds of media file images of these source indices, vital + census records, etc. 

When I restored my media files after a computer crash last year, it dated all the media files to the date of my restore, 28 April 2013. 

My question:  What do I put for the accessed date for the images no longer available or not available in the same format as the image I have.

Accessed date unknown

I have a delayed birth certificated for my grandfather issued in 1942 with his information.

In the early 1950's, his first cousin who had the same name, same first name of mother, same birth year and month and the day of month different by 15 days, applied for a delayed birth registration and my grandfathers certificate was changed to reflect the new data.  Yes, it is very confusing but it happened.

I am working on a person who was an ordained minister in the Protestant Episcopal Church in North Carolina. A great deal of historical information about his years of ministry is found in the various Journals of the Annual Convention published after each convention. All of the Journals, at least for the years covering his ministry, are available as images on The Internet Archive (Archive.org).

In 2012, I obtained many digital images of marriage records from Ancestry.com's database titled "Maine, Marriage Records, 1705-1922." Ancestry cited as their source "Original data: Maine Marriage Records, 1705-1922. Augusta, Maine: Maine State Archives."

Sometime later, I believe during 2013, Ancestry updated this database and altered its title to "Maine, Marriage Records, 1713-1937." (It's still the same database; they still cite their original data as coming from same source, i.e., with the 1705-1922 dates.)

I have a couple of questions regarding a citation for a guardianship bond, originated at the county level, but archived at the state.

I'm using 8.20 (from EE 2nd ed.) as the basic model.  My first question has to do with citing the file and document as separate elements. In this case, the bond is the only document within the file, so do I need to cite both?

My second question has to do with the repository.  The Georgia Archives are now part of the University System of Georgia, so should I include that information?

Here is what I have drafted so far:

I could not decide whether this question belongs in the Citation Issues forum or the Evidence Analysis Issues forum. For better or worse I decided to post it here.

I understand the reasons for supplying the date you accessed information on a website with the URL in a first reference note; something may have changed since you accessed it, and there is often no relevant "date posted" to use instead. But I'm having a problem with the concept of inserting an access date in a source list entry, which is normally associated with a publication date.
