I find the Quilting Board great and their links section along with Blogs from members really covers all you need to know.
I am in Australia, I buy all my fabric from "Fabricshack", "Fabricdepot", "Fabricworm", and "Quilt Kits Online" all in the US, they deliver all over the world their shipping rates are very reasonable, (buy in lots of 9 yards for Flat Rate Mailing around $14.50).
I think since I started quilting your economy is now going gangbusters.
