Well, you can load the dired package first:

(load "dired" nil t)

and then make the changes.  (The additional arguments to load are to
make it not print any status messages, so you can start emacs with
"emacs &" and have it finish loading without hanging for tty output.)
I get stuck doing things like this, because I want to modify some of
the functions in some of the packages.  A better way would be to have
a "load-hook" facility -- you can declare in your .emacs file code you
want executed after a specified file is loaded.  This would allow you
to make all sorts of customizations of existing modes.

Well, you can define a function:

(defun dired-here ()
	(interactive)
	(dired "."))

Then you can start up emacs with "emacs -f dired-here" to have dired
invoked automatically.  I don't know if you can have a function pick
up command line arguments, but if you hack around with the variable
'command-line-args', you might be able to get them.  (See startup.el.)
