Congrats on the new camera!
I am just starting out as well but I found that taking tons of pictures while systematically changing the settings (aperture/shutter speed/ISO) to see the effect on the photo was a great help.
Google the basics of aperture/shutter speed/ISO and then just experiment with the various settings on your camera.
I bet there are some youtube videos telling how to best use your specific camera.
Have fun with it!
