Welcome to ATP Amber .
Well first off my growing conditions and yours in 10B would be quite different. With you summer heat I think you would need a very large container so that the soil does not dry out. And secondly you really don't want those roots to get quite hot as they would in a smaller container in your climate.
I think it might simply be too warm for you to grow summer tomatoes in your zone and you might need to garden in the early spring and early fall to get a crop.
I did grow the San Marzano variety last year. But yup, they don't need anything different than any other variety.
They are dry and great for cooking but not for eating fresh unless you wish to add them to Salsa.
