I think I'd leave it alone for the winter - I wouldn't use a fertiliser at this time of year. If more wormcasts appear scatter them by 'sweeping' them with a long bamboo cane. Worm casts indicate lots of worms down there which is a good thing - they'll pull some of the remaining leaves down into the soil below the turf over the winter.
In the spring some sunshine and a light feed, coupled with regular cutting (and a fair degree of patience) will work wonders
PS. Try to avoid walking on it, particularly if wet, frosted or when covered with snow
