As far as the thermal falls go, I'd suggest as you head north to drive to Bagni San Filippo and do those and then head up into the Val d'Orcia to see San Quirico and Pienza before continuing along to Siena (it is Siena, although many spell it Sienna in English).
While you're in SG, I'd suggest a day trip to Volterra and to Colle Val d'Elsa and Monteriggioni.
My suggestion is to explore the area you're in without being in a hurry to get elsewhere -- and to be prepared to stop off the road when you see interesting signs, such as direct sales of cheeses (in the Pienza area) and the same for wine tastings. That is the best way to find the small wineries that are do not do any other type of advertising to get customers.
