What steps should I take after receiving approval for my 60-day visa notification for Thailand?

You should receive an email with a PDF file attached. Your visa should look like this. Print it out, hand it to the passport control officer with your passport, then check your stamp as soon as you step away from the counter. There have been many reports of mistakes recently so make sure your stamp is correct as it is very easy to fix then and there, and difficult to fix later.

Print out the Evisa email you received...

Show it to the airline staff when you check-in for your flight ✈️ to Thailand

And again on arrival into Thailand, show it to the Thai Immigration Officer who greets you on arrival.

As you have a Thai tourist visa, have you a Return ticket departing Thailand within the 60 days of your arrival into Thailand?

ASK your airline IF they will require you to show PROOF of an airline ticket departing Thailand within the 60 days of your arrival into Thailand.
