A full backup is the same as a level 0 but the latter can be used with subsequent incremental backups. Both can be used to recover. If you are using the contol file instead of a recovery catalog then you will need to have a copy of the controlfile at least.

I don't know of a way to make two copies at one pass. I would make a second copy using OS tools.

Rman is an executable and could be replaced from an OS backup. If there is a bug Oracle Support will help you.

to disk is much faster. I put my backups on tape after they are done. This can be done with OS utilities and doesn't require a 3rd party media manager which putting backups directly to disc does require.
