Emacs already filters out the uninteresting directory entries such as
"." and "..".  This happens automatically; the value of
completion-ignored-extensions does not need to include them.

What version of Emacs do you have there?  In Emacs 21.2, I type "C-x
C-f ~/foo TAB" and Emacs completes it to "~/foo/".  Another TAB gets
me "~/foo/bar/", just like I'd expect.  There are no "[Complete, but
not unique]" messages and no need to wade through useless completion
lists.

(The reason that you need 2 TABs to get what you want is because you
might wish to create a new file in ~/foo.  This is a well-documented
feature, unrelated to `completion-ignored-extensions'.)
