Welcome to ATP Ruth. I don't have advice for starting tomato seeds as this will be my first year trying also. But I do think you picked a very nice tomato variety to grow.
I guess you know that this is one of the intros from Wild Boar Farms -

They have the most interesting tomato varieties. Going to have afew of them myself this year including Berkeley Tie Dye and Pink Berkeley Tie Dye.
