I don't have a walking foot, and don't feel I'm missing out on anything (the better the basting the less the quilt can shift). FYI, you can't use a quilting guide and a walking foot together.
I'd love to know about the double needle also. I think you just need two spools and one bobbin?
I also have a Janome, and the quilting guide fits on the back of my walking foot. I could never go without my WF, it is invaluable when quilting. Marge
