It depends.  It is the TSM API (not the normal TSM backup client) that
receives the data for rman.  It sends the data over the LAN or the SAN to the
TSM server depending on how you configure it.

No, you need to configure the TSM API for SAN based backup.  Also some
configuration on the SAN and TSM server must be done.  A SAN backup is also
going directly to tape.

No, the data has to be written and processed so there is extra CPU usage and
lots of extra (read) I/O activity.
