If you're wanting to quickly set up your Raspberry Pi for web projects, check out this script from GitHub user Xeoncross: lowendscript. It was created for use with low-resource VPS servers and removes a lot of the default programs that Debian comes with that you likely do not need.
This script is great for people that are looking to do web development and other web projects on their Raspberry Pi, but want their Pi running as efficiently as possible. However if you'd like to do your set up manually, I've talked about a few web project set ups here:
Setting up Apache on a Raspberry Pi
Setting up Nginx on a Raspberry Pi
Router Settings Going to a Raspberry Pi
Nginx and PHP on a Raspberry Pi
