What are the best steps for properly overclocking an RX 580 Sapphire Nitro+?
Sounds right. Overclocking is a bunch of "guess" and check.
If you would prefer an easier solution. List out the frequency of each performance state here and I'll give you something to start with. Then you only have to test smaller changes to get your initial curve before OCing.
From a quick google search, it would seem you can expect to get up to 1500MHz. Not many results are talking about clocks much higher than that.

600MHz/820mV
900MHz/865mV
1145MHz/920mV (test memory voltage with states 4-7 at these values)
1215MHz/940mV
1255MHz/960mV
1300MHz/1010mV
1400MHz/1120mV
Maintain memory frequency at 2000MHz, set voltage to 930mV and timing to "Level 2". If unsuccessful, attempt 940mV.
I haven't extensively tested above 1400MHz, but based on my data trajectory, you should be around 1230mV for 1500MHz.
