I need help...

[Jaysmine]

I'm really excited to re-design my Vbulletin site but I've found I'm having trouble doing it. I want it to look like the attached image as far as the background and stuff goes if anyone can explain to me how I can accomplish it so it will look good in all screen resolutions...I'ld be really happy!

I want it to look like this as a final reasult:

Here are the components:

HEADER:

NAVIGATION BAR:

BACKGROUND:

FOOTER:

I need the middle part to stretch to fit the length of my message board and I'm very confused as to how to achieve this or if it is even possible.
