Been installing for 40 years. Makes no difference whether the base is on the floor or not. 3/8 is about right if you want to raise it. Most installers won't care one way or the other. It is easier to trim with a carpet trimmer if the base is on the floor. It is best if the base is down before the carpet goes in. Putting the base on top of the carpet can cause problems.
