Hi Jason, and welcome to MySwissAlps!
You can plan your trip using the Swiss Timetable:
You will most likely go via Domodossola, and your Swiss Travel Pass will be valid till there. For the rest of the trip from Domodossola to Florence, you will need a separate ticket.
There is information here that will assist you:
For your travel in Switzerland with the Swiss Travel Pass, you can download a map from the link below, showing what is covered. As explained in the legend on the map, red lines are trains, yellow lines are buses, black lines are cable cars, white lines are boats. Solid lines are free, dotted lines are discounted. Discounts are mostly 50%, but only 25% for transport where you see the number "1" inside circle near the dotted line. There are a few grey lines on the map as well, which indicate transport that is not covered by the Swiss Travel Pass.
