Citation Issues

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;

I have found two books my mother won at school as prizes. Pasted into the front of each is a plate with the date, the name of the school and the prize she won.  How do I cite this?

I have several physical certificates that I received from the GRO many years ago. I recently purchased the updated EE book, 3rd edition, revised (kindle), 2017. I then reviewed the 2-3 forum posts on citing GRO certificates.  I noted that the ones referring to citing physical certificates do not resemble the example in section 9.48, p. 474-475. So, I thought I'd best ask if views on the content/structure of such citations had changed since the book was released?

Is it my imagination or did someone say that EE nor longer requires the citation line (citing National Archives and Records Administration microfilm M33, roll 57) on the federal census because they are so readily available online? I have continued to include it but now I wonder if it is overkill.

I would like some help in crafting a citation for the following record:

I did visit the TNA in Kew last year, and looked at the "original" record at the archive. I have included a partial copy.

This is what I have come up with so far.

Enlistment record for Alexander Herd, 14 October 1793; Royal Horse Artillery: Description Books; Ordnance Office, Military Branch, and War Office: Royal Artillery Records of Service and Papers, 1793-1813; RG WO 69/2; The National Archives, London.
