Also, is it possible to change single cog wheels on such a freewheel,
rather than replacing the whole freewheel?
If the sprockets are worn, the chain is definitely toasted. You will
certainly need a new chain. Shouldn't be any issue witth the cranks.

No, not possible, the replacement parts are not available. Also, the
11-34 is a totally different mechanism than that used in the 13-34.
Shimano had to completely re-invent the freewheel to get an 11 to work.
The result is the finest freewheel ever made, and it's dirt cheap!
