Please note: this is a note from my early experience of django and the method demonstrated here is not quite beautiful, especially you got several applications under the same project. Check out my new note.
So for the template, you need to edit TEMPLATE_URL in the settings.py
Before you can use them, you need to edit STATIC_URL and MEDIA_URL in the settings.py, such as
STATIC_URL = '/static/'
Last step is to serve it when request comes, it is apache's job. Put the following two lines in apache website config file:
Alias /media/ PROJECT_PATH/media/
Alias /static/ PROJECT_PATH/static/
Then you can reference these static files in your template in this way:
<link rel="stylesheet" href="/static/css/style.css" type="text/css" />
