I'll add 2 more shops to the mix...1000s of Bolts and Whittle Fabrics. The former has high shipping, but figure it adds 50-75 cents a yard to the price and it's still a good deal.
I also recommend buying a kit at Craftsy, if you don't know where to start. Some are 50% off and really a good deal. If I were you, might start with a table runner or something just to get your feet wet before moving on to other things. Or just find something you like, as long as it's relatively easy, and jump right in.
The major fabric brands all sell good quilters cottons. Benartex, P&B, Marcus, Northcott, Robert Kaufmaan are a few of the many excellent brands.
