I will give you a very simple example how to grant select on an object owned by my schema to another schema.

SQL> /
grant select on DEPT to test_user;
grant select on EMP to test_user;
grant select on BONUS to test_user;
grant select on SALGRADE to test_user;
PL/SQL procedure successfully completed.I will try to do something like this and once I am happy with the statements been generated i will replace dbms_output.put_line with execute immediate.
Until then atleast I won't use execute immediate directly on a DDL statement.
