Wow, missing pattern lines. I'm not sure that would have ever crossed my mind.
Yes, when you get to the bind offs at the Neck shaping, stop doing the decreases.
For the decreases following the bind offs, you can use ssk and k2 tog. The nicest way to do these is to place them one stitch in from the edge on the left and right edges. (So with the RS or public side of the garment facing you, you knit one stitch, ssk, work to 3sts before the end, k2tog, k1.) Do that every RS row, 3 times.
