The materials needed for the project can all be found at Tayda.com.  It is a semiconductor store in which most things are not very expensive, but are very reliable.  You do have to create an account, but they are trustworthy, so go ahead.

Step 1: Getting Started Using Fritzing

Fritzing is a prototyping application (not a prototyping simulator) that I use to plan or record a project.  Go to http://fritzing.org/download/ and download the fritzing prototyping application.  After you download it open it (on a mac it will be under downloads).  Find the Arduino Uno part under the core parts section and drag it to the breadboard.

You can always etch your own pcbs its way cheaper than to have them done.

Thanks for the suggestion, but I do not know how to do that.
