One tip that I can give anyone who is going gluten free is to attend a Gluten Free Expo or Awareness Event. If you can't find one that is local then I would suggest purchasing a Gluten Free Survival Kit or Sample Bag. There are some great options out there. Just google and you will be amazed.
The reason why I would suggest this is because many of the Gluten Free brands simply don't taste good. By sampling the product you are not investing a large amount of your money on a product that doesn't taste good. There are many times at events that I attend that I won't even swallow the bite because it is not good.
This brings me to the creation of my Gluten Free Binder! After each of the events I attended I had a mountain of brand handouts and brochures. I organized them into a three ring binder, slipping them into clear plastic sheets. Now I am able to make notes on each brand - rating them as I go. This is really helpful for knowing which brands I want to invest in the future plus often times the brochures have information on how I can order the product and nutrition facts too!
I have mine categorized by: Business Cards, Brands, Grocery, Restaurants and Resources. I hope this helps!
