I think I may have found some of the answers to my own questions. The Leviton Vizia RF+ site for installers at http://www.leviton.com/OA_HTML/SectionDisplay.jsp?section=38039&minisite=10251 is surprisingly helpful for getting your feet wet in HA and understanding things like controlling low voltage lights and the like. The free online training on RF+ was especially useful in getting the terminology correct. For example, as a PLC guy, I never understood that a thing that looked like a "light switch" was a possible controller. I/O maybe, but a controller? I thought controllers were little bricks...
Right now I am leaning to Zwave as the products seem just a bit more professional than Insteon and not that much more money. Just wish there was a ISY-99 for Zwave, but I will start another thread on that.
