Well I'm not sure if what I use in Canada is available in the U.S.
But I would reccomend Humbrol enamel paint for larger pieces, it's a nice paint, thick and rich. However it's a little too thick to detail interiors etc. For that I would use Testors paint. Testors is also excellent for the larger parts, I use both on the large parts depending on which one makes the best colours suited to my model.
As for brush's, well I don't bother worrying about brand when it comes to this. Just find some good quality brush's (you don't need to know brand name's because you can tell which are good). Also the good one's are usually the more expensive one's, however it's not always neccessary. Just make sure you get a good fine tip brush, they come in very handy with all projects.
If the two paints I mentioned aren't available in the U.S. don't hesitate to ask an experienced modeller at a good hobby shop. I'm sure they'll help!
