ummm... how did you end up here?
first, it is sort of poor form to bump your own thread after only an hour. if you want that kind of immediate help you should be hiring someone and not depending on a free online forum somewhere
second, you're in the wrong place as this forum is dedicated primarily to the Thematic Theme framework. not to say that general WP questions don't come up, but this isn't the right place for support on other themes. you'd probably be better off asking your question at the regular WP forums:
i did write a very extensive post on menus that might be someone explanatory... but then it is colored by the fact that is is aimed at dealing with Thematic and not twentyten.
and you could also consult the wordpress codex:
or here if you could just create a 3.0 style custom menu
but ultimately you are having a problem w/ wordpress and specifically with their default theme... why not go to the source?
