Is that MBps (megabytes per second) or Mbps (megabits per second)?  The
former sounds about right.

In general, true.

Not necessarily.

If you don't have a bottleneck elsewhere (meaning that your CPU, disks,
and other parts of your system can deliver that kind of performance),
and if you have enough distinct flows to hash out over the available
interfaces, then, yes, it'll scale in that way.
