See Comma Use #1: http://grammar.ccc.commnet.edu/grammar/commas.htm Yes, those items need to be separated by commas, including the one just before the conjunction.
For lunch, she had soup, salad, and iced tea.
Last year at camp, he rode horses, played water polo, and went bicycling.
Make sense?

When I first posted this question. I din't explain it correctly and didn't find the answer I received funny. But my question is When a sentence contain a list of three or more phrases, each item should be separated with a comma. The questions is do I capitalize items such as Basic Web Design Screen, Graphic Design, Basic Web Scripting and Web Mangement.
