That's probably a good idea, but you'd want to test it.  You might also
try running a single stream to each drive (let the 3rd stream wait until
one of the other 2 are done).  Whether that's faster would depend on
what's getting maxed out during a single-stream backup.

I'm not sure what you mean here...
