I forgot to mention the coconut stuff:
Coconut flour
coconut sugar (don't really use)
Coconut flakes
shredded coconut
dessicated coconut
coconut oil

Things made with coconut flour need a lot of moisture, like eggs. There's an amazing lemon coconut slice on the Eat Nourishing site. Another site to check out is called Spunky Coconut.

Also Rapadura sugar is best if using sugars, as it hasn't been refined. Same for Celtic sea salt.

I've found that generally, GF baked goods go hard quickly, so it may be worth freezing things or making small batches.
