I prefer to use bias binding - I baste the raw edges together - instead of ironing the strips in half. That crease line is "off" as the fabric is wrapped around the edge of the quilt sandwich. Gluing might work - I found that the edges of the binding tended to creep before I secured them together.
When stopping stitching before mitering the corners - 1/4 inch is only for when one has a 1/4 inch seam allowance. If wider or narrower, use that seam allowance for the stopping point.
To the original poster - I think any of the ways you have done it is okay. Just what you prefer to do.
It does seem that there is more than one "right" way to bind a quilt.
Practicing with scraps that are similar to the real thing is helpful.
