Is Oyster also not available on National Rail between West Brompton and
Earl's Court?

Not only is it not available, there isn't a rail service.

Is pay-per-use Oystercard cheaper than... an annual travelcard?

Have had a look ...

The logic that you "can't buy a travelcard if you only travel in zone 1"
isn't exactly true since the obvious outcome of the new fare structure is
that people who just travel in zone 1 will now have to buy a zones 1 and 2
travelcard, albeit at an increase of 20% on the previous year's zone 1 only
cost. Whether this is economic depends on your number of separate journeys
per day, for example I get a tube and bus in each direction every day so the
PAYG option is unlikely to be any cheaper.
