Very nice blocks, they will have a lovely 'stained glass' look to the quilt when you are done.
I also suggest 'stitch in the ditch' for your first time at quilting. Just put your stitch length at about 3.0, no need for it to be smaller than that but it is a personal choice so you can go smaller. And yes a walking foot is a 'must have' when quilting 3 layers together.
Can't wait to see your finished quilt.
