Citation Issues

I’m privately printing my maternal grandfather’s diary written in a Field Message Book during the first two years of WWI. Among other things, I’m including scans of items in my, or a relative’s, possession. In the Reference List at the end of the book, I’m really stumped how to word the first part of a citation for a letter from my grandfather, William Robert Bruce, to my grandmother, his wife, Ethel Sarah (Phelps) Bruce. I'll just be showing the first page where he mentions being gone, "a whole year; one long year of separation."

Dear Editor;

I've stumbled upon a case which, while no doubt covered by the EE book, absolutely defies my attempts to cobble together something sensible to use as a citation. There is; an emailed PDF of a manuscript transcription, an image copy that was transcribed and an original unfinished manuscript. There are just too many different types of citation elements to identify, generate and join together.

I would very much appreciate any advice that would help me plan how to attack the production of a citation to reflect the following.

The church that has records of some of my ancestors sent me photographs of pages from the church's sacramental record books. The books have no titles and no page numbers. Would this be the correct citation? 

I want to cite a household in an1892 NY census record for Auburn NY. However I run across two issues that I have questions on.

1. There is no page numbers. Does it matter if I use the term  n.p. or unnumbered pages ? Other than line number is there something I should add to guide person to this page?

2. There is no column for relationship to say who is head of household. Is it alright if I call out the first person in the family and use their name as the household name? 

Correct me if I am wrong. A "Source List" would look like this....

Source List:

Book

Cemetery

Newspaper

Vital Record

I am in great need of a proper citation for information gathered from a genealogy society? I have gone through the book from cover to cover and on the web itself for my answer, but nothing. Can someone point me to where I could find this information as I am writing and need this greatly.

Thank you

It's a story, so bear with me a moment. I began researching my family history some thirty years ago. My father passed away when I was fifteen, so I never had a mature opportunity to question his family history. All I knew was that his father was a preacher who died before I was born, and my grandmother passed away in the far off land of Ohio when I was seven.

Hello! I have a folder of about 200 pages that has my grandfather's WWII military documents as well as forms filled out post-WWII. It's clearly part his service record requested in 1962 but I think there are other military documents he might have added so it's not quite a compiled service record? I'm feeling a bit lost in how to cite it and would love some advice.
 
To figure this out I've been reviewing EE section 3, as well as section 11.32-11.40. I've also read 

I have an interesting situation in Oklahoma. The marriage records purport to be from Le Flore county (that's what the title on the volume says https://www.familysearch.org/ark:/61903/3:1:9Q97-Y339-QSFS 

But if you scroll to the first record past the index https://www.familysearch.org/ark:/61903/3:1:9Q97-Y339-QSJ6 you see that we aren't in Le Flore county, we are in Indian Territory, Central District. Which is legally right as this area won't become Le Flore county until 1907 when Oklahoma becomes a state.

I've read over sections 12.55-12.58 in the 3rd edition (revised) on the subject of citing directories, but am still a bit uncertain as to how to shorten and consolidate citations for a span of years, especially when I've found the directories imaged online.

I believe that a typical (full length) first reference note might look something like this;
