Unsurprisingly, yes.

I was thinking of placing on the whole wrappable chunk of text.  But if
that's inconvenient, it can be placed elsewhere.  The first char of
the line sounds usable as well.

Either at the end of the line, or as soon as the text-property is not
present any more.

I'd expect the continuation glyphs to be placed in the fringe as usual.
As for cursor placement, I'm not sure what issues that entails (I can't
think of any situation where it's not clear where the cursor should be
drawn, ideally).

To some extent the implementation can constrain the design.
