Looks about right for pins. Just pick a spot to get started, lower your foot, and go slowly. Remove the pins one at a time as you get close to them. You may need to remove 3-4 in the spot where you start - just make sure the foot never goes over or up against a pin and you'll be fine. I usually remove them 3-4 inches in front of where I'm sewing. After the first couple of passes, you'll find there are fewer to remove each time. I would stitch across the middle (or near it) both across and up & down as the first 2 passes, to stabilize. Then work out from there.
It a beautiful quilt, and I'm sure you'll do great!
As you get more experience, you'll find that you can plan your pinning to minimize the number of pins that will be "in the way" on any pass which will speed the process. But there's nothing wrong with what you have done for this one.
