Forgot to mention, this was one of the first things I checked. How badly stretched is "badly stretched"? I think mine, after a quick measurement with a digital caliper, is 3.216 inches instead of 3 inches, which to me is pretty badly worn! I have been very bad with maintenance this year

You need to change your cassette and chain anyway; do that, and if you are still having problems come back and get help. With all of the adjusting you are doing now, start over from from scratch after you've installed the cassette and chain.
Well to be honest, the skipping just seems to be the derailleur not moving enough to get the chain onto the next cog and the chain skipping between the two. When I adjust the cable then the shifting is perfect with no skipping.

Pay particular attention to the lower loop of housing going into your derailleur; it tends to collect dirt and crud. Dirty or poorly-installed cables and housings are a frequent cause of shifting woes.
I will check out the cable, was thinking of replacing it anyway. The cable and chain haven't been changed since I bought the bike (about 10,000 miles and 3.5 years ago!) so I was going to get together a shopping list.
Thanks for the replies,
