Kevin, The brackets and track show what you plan to do very well. My wife doesn't have to worry about me leaving a mess. She admits I am actually neater than her. 
Growing up my brother called me a Neat-Nik like a Beatnik. He was the next thing to a slob. It was interesting sharing a room with him! 
Will, you are another modeler who recommends birch. I bought a number of birch 1x2s, and they do stay true!!
