Well the 2 errors are because:
1: there is no background attribute for the td tag take it out
2: there is no alt attribute for a td tag :- take it out
design wise I could add some padding to you menu apart from that it looks ok. nothing outstanding but it works.
Code wise you need to drop the tables and start using an external style sheet to style everything. Doing it without tables you could cut down your html code to a quarter of what it is now.
