There are several online resources available for these technologies. Just google for it. I also suggest that you look up some of the quality indormation on http://www.soapui.org that cover it in detail.
Also recommend your attending Introduction to soapUI Training course on how to thoroughly test Web and REST services because it has a lot of hands-on lab work. When I spoke to Schnieder in Bangalore for Saltmarch BT Summit, he said the training covers how to use soapUI to test SOA, Web and REST services for scalability, performance and reliability.
Saltmarch also does an Advanced soapUI Pro training course. For training details check http://www.saltmarchi.com.
