I went from knowing absolutely nothing 2.5 months ago to now being an amateur, what helped me a lot was getting the three basics down.... Shutter speed, ISO and aperture.
Learn what each of those do and you'll be set to start. A TON of information is just in the manual, read it a dozen times or until it sticks.
One thing you'll need to learn is that your camera is not that smart when it comes to exposure. Once you get out of auto you'll never want to go back. Don't jump straight into full manual like I did.
Start off with AV or TV mode.
AV is aperture priority play around with that, get close to a subject go wide on the shot and set it to 3.5. Now take the same picture at 5.6 and see what happens. Experiment with it.
TV is time value aka Shutter speed, test it out with a moving subject. Set the speed to 100 and see what happens then bump it up to 250. Now down to 10. You'll begin to learn how to time you shots to capture the moment.
The focus is another story, leave it on auto. There's no need to go manual 95% of the time, you will have to under certain conditions but stick to auto for the time being.
You can manually choose which focus point to focus on, go into your manual and look that up. Choosing the center point or one off to the side is a good place to start. Then your camera will only focus on that point instead of metering the whole plane to find something with contrast to focus on.
