Begginer Help

Hello,
I am a Solidworks 2010 user and am looking into getting into CAD/CAM CNC. I currently do all manual machining (lathe, mill, grinding) and have a need for CNC. I am trying to get all this straight please take it easy on me. I have the CAD software and I am working on a machine. Next I need to get a CAM package to interpret my CAD models??? Then if I am going to use my computer to control the machine I need a control software??? I know there are lots of other details, just trying to get the basic idea down right now. If anyone has any advice I would appreciate it. Thanks.
