Need help planning garden layout?

I'm planning on having a vegetable garden this year, and need to know the best place to plant so each variety gets the best sun/soil combo. I plan to make raised beds, but not sure with what material yet. Cheaper is better. The garden would include herbs, veggies, and root crops, pretty much anything I eat on a regular basis. Potatoes, peppers, onions, lettuce, corn, cubers, green beans, pumpkins, watermelon, etc. I have a large area to plant, but tall pine trees surrounding my yard that shade the area inconsistently. I live in Eastern WA, so the summers are super hot and the winters freezing. What crops should I plant next to each other? I heard growing the corn with the beans helps them to stabilize and reduces the need for trellis or stakes. Where should the corn and beans grow? To the North, East, South or West of the main beds? Thanks!
