Because the squash cooks quickly, you'll be breading, flipping, and removing pieces at the same time. Don't wait until every piece is in the pan before turning the first ones over. Think of it as a continuous rotation rather than cooking one full batch at once.
Some of the breading will fall into the oil during cooking. I find the oil is usually good for about 2 medium squash before it needs to be strained or replaced.
The oil should be around 350°F. I don't usually use a thermometer; I simply make sure the oil sizzles when the squash is added. To test the oil, sprinkle in a little flour or place the handle of a wooden spoon in the oil. If bubbles form around it, the oil is ready.
