I'm brand new to LaTeX, looking for some guidance.
I have read a couple of the introductory books/documents, done a bunch of simple tutorials, and got basic examples/documents working fine. Then I've spend a couple of days trying to achieve my real typesetting goal, without success

Here's an image of roughly what I'm trying to achieve:

The yellow highlights aren't important, but what you (hopefully) see here is that my document contains three main "classes" of text:
1. The text which is the subject of inquiry (shown in blue),
2. A long list of commentary/notes about 1 (shown in black), with groups of notes appearing directly under the relevant sections of blue text, and
3. A collection of quotes and citations occurring within 2 (shown in brown). Almost all of these quotes/citations are from other sources--but a few refer to other notes in the current document as a "see note 334" reference.
I have played around with fbox, minipage, footnotes, endnotes, verbatim, cross-refs, but I can't seem to find a basic document structure that will support output like this. Most of the packages/commands I have seen want to render all the notes at the bottom of a page. Minipage looked promising (and perhaps the answer is there somehow?), but it doesn't seem to want me to use numbered notes across the broader scope of the document. I also read that minipage doesn't allow floats, which might be a problem further downstream.
So... is there a neat/obvious way to structure a document like this:
subject-text including notes
notes including citations
---
subject-text including notes
notes including citations
---
subject-text including notes
notes including citations
---
Etc.
With annotation numbers running throughout the whole document?
I'm sure the problem is between the seat and the keyboard, but any pointers would be much appreciated!
Thanks
