When I moved out of my parents home, I had a good job, a sleeping bag, metal tray table, stereo, lava lamp and some towels. I didn't have a bed for about a year or any furniture for quite a while after that. They were some of the happiest days of my life.
You'll need a place to move into. Inexpensive furniture (unless it's a furnished room like a dorm). Bedding, food, money, list of utilities you'll need to contact (phone, electric, gas, water, cable, etc.), more money, friends to help you move, utensils, basic tools, more money, emergency contacts and bandaids ;p, a microwave, to find out whether you'll need to furnish other appliances like refrigerator, basic non-perishable food, transportation, and even more money.
