They both go over many examples of how to connect the Seeeduino GPRS and even provides some sample code that you could run to test the connections if you are still unsure. As for the relay module, it depends on which one you are using, the LCD can be easily connected following this tutorial: https://www.youtube.com/watch?v=85LvW1QDLLw. Hope this helps.
