So it looks as if the battery is OK, but it is not charging properly. I obviously have to take it to be repaired - but what can they do? I understood that they can't replace the battery, so what are the options? It has only been through 377 charge cycles - that doesn't sound a lot to me - but is it? Shouldn't a laptop that's only just over 2 1/2 years old still have a perfectly good battery??

Over a very large sample of laptop batteries, yes. You do not have a very large sample, you have one laptop, and it could be doing anything.
Make an appointment to visit the genius bar at your local Apple Store. The evaluation is free and they can lay out your options once they get a chance to test your Mac. Bring the power adapter as well. Back up before you go, in case they need to keep it overnight.
