GTT and Undo and Redo

Quick question or clarification :
No Redo is generated for an Insert into a GTT There is Undo generated

Questions :
If we do a Direct Path Insert / Parallel Insert into the GTT can we avoid/reduce the Undo as well (and the Redo for the Undo) ?

If there is an Index on the GTT, undo is generated for the index as well - what about a Direct Path Insert ?

How does this work in a FORCE_LOGGING database ? Does it force redo for all direct path operations against a GTT and Index on GTT ? My Test environment doesn't have FORCE_LOGGING (and I am not the DBA) so I can't test this.
