This is my first time paying/filing for taxes.

Starting April 2013, I started getting paid as a part time independent contractor. When I get paid, nothing is withheld.

I have no idea when to pay taxes and how much to pay. What forms do I have to fill out?

I know that this January is "tax season" but that seems to be for returns, not actual payment of taxes.

I read the various forms on the IRS website, but it's so damn complicated. I'm not sure if I need a 1099-MISC, a 1040A or 1040EZ or 1040ES or a W-2.

Heck, I don't even know what type of taxes I need to pay. Income? Self-employment? Social Security?
