You can also freeze tomatoes whole and save to use in sauces and stews throughout the year.
If I were you, I would invest in 2 wonderful cookbooks. They are "The Splendid Table" and the "Italian Country Table." Both of these are written by Lynne Rosetto Kasper. She has some amazing dishes that utilize tomatoes and she has excellent hints for tomato storage, etc.
She has recipes for several tomato sauces, roasted tomatoes, dried tomatoes, etc. She even has a recipe for a wonderfun green tomato sauce to use "on a midsummer's eve."
My favorites are her Oven Roasted Tomatoes, which are roasted with olive oil, fresh basil leaves, rosemary, onion, and garlic. They are out of this world.
Honestly every reciipe we have tried in these two books has been wonderful, without exception. I highly recommend both of these books. Her recipe books are endorsed by people such as Alice Waters, Mario Batali, Luciano Pavarroti and many others.
