I am working a pattern that is done in stockinette stitch. How should I knit the first stitch? Slip, knit all (even on the pearl row), pearl all (even on the knit row). My edge is very bumpy. I have been knitting or pearling according to the row.
This pattern at the edge (basically one st in garter stitch on each edge) is often described as a selvage edge.
It is usually added to reduce the amount of curl at the edge and to create a firmer edge for sewing the seams on your garment.
You don't have to add it if you don't want to, it will just mean that you do not gain the benefits of having a narrow selvage edge on your knitting.
