I recommend xchrisd’s 3D Print Guide. It starts out fairly non-technical, but dives in pretty deep. Feel free to skip over sections you’re not comfortable with now, and come back later when you’re more experienced.
First layer adhesion can be a couple of different things. You appear to be underextruding a bit (the first layer should be a continuous sheet of plastic, with minimal ridges. Your first layer appears to be a bunch of strings laid side by side, so I’d like to see wider strings that join together).
But that could also just be a calibration problem, and the nozzle is too high off the bed. The recommendation I’ve heard is to warm up the bed, and calibrate with the highest number of points available.
You might also check out flat your bed is. Get a straight edge and a flashlight. Put the straight edge on the bed, edge down, and shine a flashlight from behind towards you. Look for any light escaping under the straight edge – that part isn’t flat. For major gaps, try to flatten the bed by adjusting the mounting screws. This will also give you an idea of how many calibration points you need. If the bed is very wavy, more points. If everything is pretty much perfect, fewer points are needed (even if the bed is straight, that doesn’t mean it’s parallel to the base plate).
You shouldn’t need to modify any of the Luban parameters yet. The included Vase ought to print once you have a good extrusion and calibration.
Lastly, welcome! A failed print is pretty much everybody’s first rite of passage.
