newbie very frustrated with simple CSS

http://messiah.scojul.homedns.org

Two problems:
1) UL does not display below header DIV in FF, looks OK in IE6
2) UL list items will not center in FF or IE.

I had a hard enough time getting the stupid gif and text to display on the
same line, and now this...I'm going to go nuts... It shouldn't be this hard,
should it?

Grrrrrr...

Thanks.
