How do I handle bottlenecks and personalities on a warehouse shift?

You can run a shift now, which is no small thing. The bottlenecks and the personalities trip you because they are the messy human part, and that part does not follow the same rules as the work itself. Bottlenecks are usually easier than they look once you stop reacting and start watching. Most floors jam at the same few spots every day. Learn where yours are and you can see the jam coming before it forms. The personalities are harder, because you are not moving boxes, you are working with pride, moods, and history. Pick one recurring bottleneck and one difficult person, and handle just those this week. For the bottleneck, plan for it before the shift instead of fighting it midstream. For the person, have one calm, direct word away from the crowd. You do not have to master every jam and every mood. You get steadier by clearing them one at a time.
