That's the obvious part.

I don't understand: presumably your ~/.emacs.d or ~/elisp dir will be added
to your load-path by ~/.emacs, so you don't need it on the command line.

Again, I don't understand what situation you're thinking about.
In my view, there are mainly two cases:
- single file packages, which you can handle with "emacs -l /where/ever/foo.el"
- multifile packages, which have an "autoloads" or "site-init" file and
  that file should set load-path for you, so
  "emacs -l /where/ever/autoloads" will again take care of the load-path.
