Answer 1

You should use the dbms_lob package, the procedure to add some string to the clob is dbms_lob.append.

DBMS_LOB documentation

declare
  c1 clob;
  c2 varchar2(32000);
begin
  c1 := 'abc';
  c2 := 'text, which contains 32 000 characters';
  dbms_lob.append(c1, c2);
  c2 := 'some more text, which contains 32 000 characters';
  dbms_lob.append(c1, c2);
  insert into t1 values (c1);
end;
