Hi!
The beauty of DSLRs is that they have a lot of settings and features - but the downside is that you have to figure out what they do, and choose the ones that you want, in order to get the photos you want!
So I recommend you keep the recommended settings from that review and experiment, until you know exactly why you have each setting. The idea of the recommended settings is to give you a good place to start, and then you can grow out of them! It takes some time to learn all of that, but since you have the recommended settings you are not in a rush
Great camera you have there, good luck!
