I'll make some general recommendations:
Thinner- Appropriate thinner for the paints you are using.
Gloves- Use solvent resistant(don't use laytex if using non-acrylics) to clean the airbrush without getting thinner on your hands.
Microbrushes- Tiny brushes that can be used to remove paint from small crevices.
Here is a great airbrush cleaning kit.
