So my next task is to learn about the HTML preamble.
From reading the docs, it looks like all of my org files have to share a
single HTML preamble, which is set in my .emacs file through either the
org-html-preamble variable, the org-html-preamble-format variable, or the
org-publish-project-alist variable. There is no way to tell a specific Org
file "This is your HTML preamble." Is that correct?
Why are there two different variables org-html-preamble-format and
org-html-preamble if the org-html-preamble variable can perform all of the
tasks of org-html-preamble-format and more?
Finally, how do I get the current date into the preamble? I see that I can
specifically set a date, and I see the current date in a comment at the top
of my exported HTML, but I can't figure out how to get the current date out
of the comment and into my preamble.
Thanks.

That is incorrect (IMO). On a file basis you can turn off most preamble
things via the relevant OPTIONS keyword.
On a project basis you could set the relevant variable. See
org-publish-project-alist.
I guess you could make a clever function that sets the org-html-preamble
based on some heuristics and add it to one of hooks that are run before
parsing. See e.g. org-export-before-parsing-hook.

org-html-preamble-format is a template, it seems, that is used by
org-html-preamble, which can also take a string or a function. In
practice I always use org-html-preamble in ox-html projects.

Hmm. Does %d or %C work? See org-html-postamble-format.
Hope it helps,
Rasmus

I don't know if this helps, but I have postamble requirements in each
file that I export. I believe you can do the same for the preamble.
Below is an example from one of my files.
----
* COMMENT Postamble Settings
#+BEGIN_SRC emacs-lisp
;; Turn off postamble creation
(setq org-html-postamble nil)
;; Turn on postamble creation (default)
(setq org-html-postamble t)
;; Postamble format for lessons
(setq org-html-postamble-format (quote (("en" "<p
class=\"author\">Author: %a </p>
<p class=\"email\">Email: %e</p>
<p class=\"creator\">%c</p>"))))
;; Postamble format for non-lesson pages (default)
(setq org-html-postamble-format (quote (("en" "<p
class=\"author\">Author: %a </p>
<p class=\"email\">Email: %e</p>
<p class=\"date\">Date: %T</p>
<p class=\"creator\">%c</p>"))))
#+END_SRC
