I would strongly suggest you take your bike, pedals and shoes back to the LBS where you purchased the pedals. They should willingly install the pedals and cleats for you. Also, have them put you on a trainer and talk you through the whole process of clipping in/out. I do this with every customer that wants to learn about their pedals. Some customers just want to do it all themselves, but I still offer the service - actually I have all of my employees do this for any customer.
