Great lifestyle change. I have been vegan for 2 1/2 years. The book "Eat to LIve" by Dr. Joel Fuhrman is a great resource that I think you may find very useful for your new lifestyle.
Processed vs. unprocessed foods: I look at the fiber content. If its not a fruit or vegetable or bean I generally only eat it if it has 4 or more grams of fiber per serving (a serving being at least 100 calories and not more than 250 calories). The exception to this? Soymilk and tofu. If it has a high fiber content its pretty unprocessed. Grape Nuts pass this test, Cheerios do not.
As to your shopping list - looks pretty healthy. I'd make sure and add a lot of fresh fruit and veggies.
