Cotton swaps and Windex for cleaning the airbrush.
You can buy 5 liters of sprinkler fluid for the car at your local gas station and it will last you a life time.
Windex/sprinkler fluid can be used as both a thinner for your paints and as a cleaning agent.
I suggest you buy some "real" airbrush cleaner (from Vallejo, for example) to "finish" the cleaning.
You WILL need some airbrush cleaning brushes. Pipe cleaners are too big. Go buy those online right away!
If you feel that a mask and/or a well-ventilated area isn't important I suggest you paint for a bit....and then blow your nose. Nothing will make you worry more about proper protection than that.
Other than that, I suggest having things like tooth picks, a mixing palette, plastic pipettes, a variety of squeeze bottles and a big roll of tissue paper handy.
A cadboard-box with a side cut out will function fine as a backdrop/spray-booth.
