I accidentally ovefilled my  6-cylinder Outback with too much oil--probably about a quart too much. Will that do any harm? Do I need to drain it off (a pain for me to do)?

If it was mine I would drain the oil out. To much oil can cause all kinds of issues that are a lot more of a pain than just draining out a quart of oil. IMO anyways.

Yes drain it out, if your oil filter is easy to get to remove and drain it, then reinstall it, start the engine, make sure there are no oil leaks, shut it down and recheck oil level, if it is still too high do it again.
