My wife and I are Seniors traveling by train from Rome to Naples to Florence to Como and then on to Zurich - April 27 to May 7. We have 2 or 3 days in each location. What would be the best way to get train tickets.
For purchase 90 days in advance only
Rome to Naples and Naples to Florence
I 'd use either https://www.trenitalia.com/it.html or https://www.italotreno.com/en.
For Florence to Como to Zurich use

When you say Como, do you mean the city of Como, or some other location on Lake Como?
Como City, we'll take a cruise from there.
