Almost all my quilts have fleece backing and I quilt and bind it instead of birthing it. I do safety pin basting and that works well for me. I do not use batting with fleece. I agree with the others that it is probably better to tie a quilt that has been birthed, but if you do quilt it, use a lot of pinning or basting to help you hold the two layers together. For quilts backed in fleece and no batting, the quilting can be quite far apart as all you are doing is securing the two layers together. Often I just outline quilt the squares or blocks.
As far as piecing the backs, I do it all the time. How I do it depends on if I need more width or length or both. As a rule, I will make a cut to one side, perhaps 1/3rd of the width or length, add a strip of fleece between the two sections, and using matching thread I stitch down the seam with a very long narrow zigzag.
