Usually it's a good idea to learn how to paint and what kind of equipment to purchase BEFORE you're painting your pride and joy.
I suggest a good general purpose compressor - not an airbrush compressor. I second the detail gun.
I also suggest you build a Sig Kougar, glass and paint it and put your Corsair aside until you feel like you know what you're doing.
