How do I file my taxes (read all)?

I have never filed taxes before and last year I started writing for a website called Demand Studios. I made about $960 for the 2008 calendar year and they sent me a 1099 form stating my non-employee compensation. They sent one for me to give to the IRS and the other for my records. I am so confused on what I am supposed to do with this. Could someone please help walk me through the process I am going to have to go through to file? I have no other income besides child support. Isn't child support non-taxable? Does that mean I do not have to claim my child support?
