Answer 1

With Hibernate's NativeQuery, you need to return a ResultList instead of a SingleResult, because Hibernate modifies a native query

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id

like

INSERT INTO bla (a,b) VALUES (2,3) RETURNING id LIMIT 1

if you try to get a single result, which causes most databases (at least PostgreSQL) to throw a syntax error. Afterwards, you may fetch the resulting id from the list (which usually contains exactly one item).
