Creating school website! Need suggestions!

Okay, I am an intern now with the computer administrator at my high school now at Emery High in Castle Dale, Utah.

I'd love to use a PHP front end software to make things a little easier and then ill create the graphics/skins over that... I remember long ago I used PHPstar and some others...

I'm just wondering if there are any web geeks out here that can point me in a good direction of what I should probably try out.

I've installed PHP and MySQL on the schools webserver so we should be just about ready to go with anything.

thanks!

any help is appreciated!
