Tomato question

Tomato question

Okay, this is probably an astonishingly stupid question, but I've never grown veggies before, just herbs. I have roma tomato plants. They are starting to flower. Should I let them flower, or should I pinch back the flowers? When should I start seeing indications of fruit? BTW, I've also got an alpine strawberry starting to berry. I'm so excited about that!
