New to forum and looking for some info

Greetings all. My name is Harry and I am new to the forum. I have built models all my life, but nowhere near the detail you folks put into yours. I want to try one though. I was given a 1/350 scale model of the USS Enterprise CVN-65 with the old style bridge and mast. I have found a few web sites where I can order period aircraft. A few questions though. First, the model is molded in a dark gray. What is a good color to paint the model that would accurately reflect the actual color. Keep in mind that I don't have any type of airbrush equipment and am not planning on buying any until I see how my patience goes with this model. Second, where can I get decals for the aircraft. Thanks for all help. Any body with any ideas is welcomed to contact me via email at harry.twiford@norfolk.gov.
