let me chime in a little ;-)

No idea, I never observed spanning- tree behaviour of vswitches

It doesn't have to.  It can not be configured to create loops, so we don't need to spanning-tree to protect against them.  Externally, it appears as a normal ethernet port, so the real switches at the other end of the cable can do their spanning tree stuff, if they're so inclined.

Turning it off completly should'nt be supported on any switch.  I assume you mean turning off the spanning tree checking before taking a port online.  Cisco switches used to do this, and you could turn this off, as in "go online first, check later, then, if loop detected, take port offline".  This would speed up the onlining of ports, but not disable spanning tree checking completely.
2. How can the bandwidth that a VNIC consumes be limited?
  (Case: we're creating multiple non-global zones in 1 LDOM guest and
  want to prevent that one non-global zone can take up all bandwidth for a
  single VNIC).
OTOH no way to do this in an I/O domain only without Crossbow. 

you'll need crossbow for that, as martin already said.
