I wouldn't worry about how to install each new component. Being a good technician isn't about knowing details about components. It is about being able to find the information you need quickly and efficiently while maintaining good troubleshooting habits.
If you don't know about DDR3, no sweat. You can figure that out if you understand RAM in general. If you don't understand a technology you need to begin to read up on it and learn more.
One really good way to start to get your troubleshooting skills up is to answer questions in the free clinic here on this site or go to http://answers.yahoo.com
and answer tech questions there.
Do the research, be sure to list your sources and you will find you begin to troubleshoot faster, more accurately, and results will show.
Another huge part of being a technician is being confident when you talk about what you are fixing. Do not let the person bringing you the computer tell you what to do. Instead listen to them for clues about the problem and using your skills begin to work through the issues.
