No.  Won't generate any "undo" either.

Yes. /*+ APPEND NOLOGGING */

Why not use the built-in parallelism of Oracle?  Unless you've left
PARALLEL_MAX_SERVERS at the default of 5, you can add the PARALLEL hint to
both the INSERT and SELECT clauses.  You might also want to precede with
ALTER SESSION ENABLE PARALLEL DML and (of course) succeed with a COMMIT...

    alter session enable parallel dml;
    insert /*+ append nologging parallel(x, 4) */ into <target> x
    select /*+ full(y) parallel(y, 4) */ ... from <source> y;
    commit;

No faster way to clone.  Your mileage may vary, but if you have a decent
sized box it shouldn't take more than 60-90 mins, tops...
