I agree with everyone else that it looks extremely outdated, but I'll try to do my best to give you a few tips. I'd take enigma's advice and just practice basic design concepts, because there is a great learning curve.

I see some of your biggest design issues are:

1) Visual hierarchy
2) Color
3) Spacing/margins/effective use of whitespace

Here are some resources to get you started:

Colors, General Tools: http://webitect.net/design/5-tools-f...b-designer.php
(sorry, I'm not trying to shamefully plug my own blog, I just feel the resources in this post I wrote could help you out a lot, especially the Color Scheme Designer 3)
