How many tomato plants do I really need?

I thought my new Vegetable garden was huge, till I started filling it in :) I am getting low on space but have yet to plant any tomatoes. I have started several peat pots and realize I might not have enough space for them all. Here are a few questions; *How far do tomato plants really need to be? *There are 2 of us here, but we eat loads of salads and pasta in the summer. How many do you think would produce enough for us? I am planting Romas, Legends and Cherry. *Any tips to make this tomato growing thing easier? I live in Seattle, face full west and the garden gets about 6 hours of full sun daily! Whew! Thanks for reading all that, and Thank you for any help in advance!!
