What do I need to buy in order to paint the walls and ceiling of the rooms in my apartment?

Never did it myself before. I know that you use different paint on the ceiling then the walls so that the ceiling is shinier. Other then that, I don’t know specifically what to buy, how many cans to buy, what brushes, rollers and how many… For quantities, base it on ONE average room. I’ll calculate from that.

I’m looking for fast and easy.
