tomato plant trimming

Question

My tomato plants are, I fear, way too big and overgrown, and are suffocating my other plants from the sun. Can I trim them without harming them?

Also, I heard marigolds affect them, but I forgot how except that the effect was positive, so I did so. How does it affect them?

Marigolds can help deter pests in the garden! I plant them at the edges of all my raised beds, and they look pretty too!
