Affiliate Marketing Secrets

I am a 17 year old. In 2010, I have made a total of $7106.63 by running a small blog online, and being a part of affiliate programs. I received my 1099-MISC’s in the mail and I am ready to file my taxes for the first time. My father still claims me in his taxes, but I plan on having my taxes managed separately through his tax preparer. I know that the Self Employment Tax is 15.3%, but what other taxes will I have to pay? I live in Nevada. How will I be able to pay the IRS? How does that work?
Can I also deduct:
-Domains I registered
-Computers
-Desks
etc.?
Please help! This is all new to me! Thanks!
