I think the others have given you the advice need on the model. Tamiya is always a good place to start. As for the air brush, badger is a good place to start. It will give you the hang of an air brush, a good finish and without spending big $$$. Lastly as far as the compressor, I would look at Home Depot Or Lowes. A small "pancake" compressor is fine. You will need a few fittings which should also be available at the same place.
