1) How does it perform in fast bumpy corners? In loose corners, I often lean
the bike way over while staying relatively upright myself (ie off the saddle)
Isn't the beam bike just as likely to get knocked off line in a corner as a
rigid bike? Indeed, is a suspended bike (rather than a suspended rider)
system any better in this circumstance? I have only briefly tried the various
systems myself.

To get the most benefit from the beam, it seems you need to learn to sit more,
(like riding a motorcycle).  If you stand, it behaves the same as a rigid bike.

2) Is the reduction in standover height a problem?

I haven't had a problem with this,  But I have stumpy legs and have had 
a lifetime of bikes that were too big. if you find yourself standing over
the top tube a lot, this could be a problem.

3) Does a beam bike benefit from lower gears to facilitate a "sit down and
spin" riding style, to get max. use from the beam on rough climbs?

I ride a 24x30 low gear on my rigid bike and try to sit on climbs anyway, the
beam bike did seem to have better traction on climbs.
