Couple of comments:
1) get rid of the word homepage. Take it out of the Header, and change it to the word Home on the button.
2) dark blue link colors on black background = can't read a damn thing.
3) frame up your prologue to be more 'center of page' and less wide. Clean up the carriage returns.
4) as a corollary to #1, get rid of the name of the page you're on from the header. Instead have the 'button' darkened depending on which page you're on.
5) Good luck!
