What should a developer know before building a public web site?

I gotten interested in web-development lately. I am still a student. I learnt basics of HTML, CSS and JavaScript. Then I thought I should improve my server side scripting. So I am learning Struts2 and I am doing better there. Now I have decided I should finally put my skill to some use.

So my friend and I have decided to come up with a fun website for our class. But now I am realizing that, though I know server-side scripting to a good extent (not great, just good considering I am a beginner), I am nowhere near good in the basic elements viz. HTML, CSS and JavaScript. I mean, I can't do cool stuff with it.

I am aware of w3schools, but it would be great if you can point out a more intuitive place where I can learn to do all the cool stuff in a short time.

Some of the problems I am facing are:

1) How should I design the basic layout of my website?

2) How can I use 3rd party APIs like that of Facebook graph?
