If you have a Whole Foods near you, grocery shopping might be a little easier. Some of their wheat free/gluten free products don't taste to bad. Just make sure you find out all the different names used for eggs, wheat, milk and corn. Luckily those are pretty common allergens, so you should just have to avoid products that have the warning "may contain..." or "contains..." 8th Continent is a very good soy milk, closest I have found to the texture and taste of cows milk.
