do you do the same adjustment at each course of attack (broad reach vs. close hauled)?
Almost never. It is usually a set-and-forget setting.
For course racing, we set the jib leads to get the jib breaking evenly upwind. Downwind, the crew hand holds the jib sheet in light/medium wind to keep the telltails flowing evenly (and this usually requires that she sits right behind the front crossbar and holds the jib sheet out to the side of the boat and moves her arm up or down to keep the top flowing properly). In higher wind she trims straight from the cleat, usually sitting back on the tramp.
For casual sailing, it's really not worth the hassle to mess with the jib leads. But if you wanted to experiment, you would probably end up moving the jib leads forward for downwind since the top of the jib has a tendency to twist open too much downwind.
