NLB32, spd's are pretty easy to clip in and out of.

I recommend going back to your bike shop and have them install and align the cleats for you. They'll probably do a basic fitting for you at a nominal price. I don't recommend beginners try to install and align their cleats.

Your fit on the bike is very crucial and the help of a shop can save you many an ache and pain, and even prevent serious injury down the road. Quite literally. Best wishes, and welcome to the sport.
