Hi, I'm putting this in a thread of its own so maybe you'll get a bit more response.
Since you have a carte de séjour, I think you actually may not need a visa to visit the UK. The fact of residing in France is supposed to give you leave to visit other countries in Europe (maybe that's only in the Schengen region). You may want to check with the consulate on that.
But in any event, I don't think there's any problem with your cds expiring at the end of October. Just be sure to start the renewal process as soon as you get back from your visit to the UK.
Cheers,
Bev
