As an Emacs beginner, I am working on writing a minor mode. My current (naive) method of programming elisp consists of making a change, closing out Emacs, restarting Emacs, and observing the change. How can I streamline this process? Is there a command to refresh everything?

You can use the command load-file ( M-x load-file , then press return twice to accept the default filename, which is the current file being edited). You can also just move the point to the end of any sexp and press C-x C-e to execute just that sexp.
Press M-x and select doom/reload to apply the changes; If changes doesn't apply, close and re-open the Emacs.
In a fresh Emacs window, type ESC-x lisp-interaction-mode . That will turn your buffer into a LISP terminal; pressing Ctrl+j will feed the s-expression that your cursor (called "point" in Emacs manuals' jargon) stands right behind to LISP, and will print the result.
function (aka #' ) is used to quote functions, whereas quote (aka ' ) is used to quote data.
You might try using M-C-x (eval-defun), which will re-evaluate the top-level form around point. Unlike M-x eval-buffer or C-x C-e (exal-last-sexp), this will reset variables declared with defvar and defcustom to their initial values, which might what's tripping you up.

Also try out C-u C-M-x which evaluates the definition at point and sets a breakpoint there, so you get dropped into the debugger when you hit that function.
M-x ielm is also very useful as a more feature-rich Lisp REPL when developing Emacs code.
