Just had a read of your blog

I get gluten, egg and dairy free muffins they also have crumpets from Coles. The brand is called LivWell and my Coles stock it next to the normal muffins. They are expensive. I have taken to not worrying about cost of products as it would really stress me out if I did. I also think that since he can't have so many things that he can whatever he wants in the things he can have.
I struggled with the baking as well.
In the end I used a Basco cupcake mix that was gluten free and you adjust the ingredients you add to make it dairy and egg free. It worked well.
The place I shop at also delivers. It's called absolutely gluten free (in werribee victoria). Worth having a look at their website even if you don't purchase as the product range is huge and you can reduce your search by diet.
The brand of icecream I get is called Cocoluscious, he absolutely loves it and it does taste nice!
The pasta I get looks exactly like normal pasta and it tastes ok as well. DS2 doesn't really know the difference and my others kids eat is as well.
