If you have a Super Walmart in your area, it's worth the drive out there. Their GV brand puts gluten free right on the label. That's where I do ALL my shopping now. You can save a lot of money by being able to buy the generic brand of things. Plus, it really opens up some new foods since you don't have to call the company every time.
I would also suggest buying a few good gluten free cookbooks to get you started. I still use mine all the time for baked goods. I recommend Incredible Edible Gluten Free Food for Kids by Shari L. Sanderson and any book by Bette Hagman. Those are my favorites. The cookbooks are a really big help in the beginning so you can see how many delicious foods you can still have.
