Calibration means setting to a standard, but there are many choices. When you get your calibration hardware and start the work, you have to make many choices. I can help with a few.
I think defualt "monitor contrast" is a good choice for LCD/s
Gamma is usually set at 2.2
6500 seems to be the choice for white Balance.
Brightness is the one hard choice so I will supply options.
For printing, I like a dark monitor, 80cd/mm^2.
For web presentation, you will want brighter, like 120 or even 150.
I use the McBeth color checker to make camera profiles and have paper profiles for my printer from the manufacturer. This seems to work well.
But if your monitor is wide gamut and you are not normally viewing sRGB, your web presentation may not look good in the sRGB world of web. And if you calibrate dark as I do, its almost a waste of time to show your work on the web.
