I drop all random .el files in a single directory and compile only Org
stuff.

Yep.

Yes, I also use relative paths but I do not use any functions to expand
file paths/names.
GNU Emacs 22.3 ships with org 5.23 and I have always been loading org
like so:
(add-to-list 'load-path "~/elisp/org-mode.git/lisp")
So my org path must be coming after system without any issues. So how
come I always get git version loaded (never 5.23), although
emacs-22.3/lisp/textmodes has both org.el and org.elc? Ah.. I see GNU
Emacs doesn't have site-start.el like EmacsW32 does.

Shouldn't this be (require 'org-install)?

This looks quite useful. I will try this out.
Thank you
