Which readiness code isn't set?
And yes, disconnecting electrical power (or clearing fault codes from the ECM) will reset the readiness codes.
The drive cycles are pretty generic and shared with similar vintage GM passenger cars. You should have some luck with a search of the internet.
The catalytic converter ones I did with a Tech2 plugged in and was able to nail them very quickly, as there's one that basically wants some stop & go driving, and I just pulled over immediately each time the tool showed the test was ready to run. It also made the steady state cruise ones easy because I was able to monitor completion in real time.
For EVAP, you may also be able to trigger the service bay self test with a tech2, but success there depends on the internal details of your ECM. Knockoff units from AliExpress work great for this, and can be found in the $150-$200 range.
If you can't trigger the EVAP cycle with a factory scan tool, the key is basically driving it every day very specifically. The tank can't be totally full, nor mostly empty, you have to have certain starting temps, etc, etc. Took me about a month to get that particular code set specifically. Referee, unlike a normal smog test, requires all the readiness monitors to be set to pass you.
