Yes.

No.  You can do 'ssh over ssl' though.  And there is a good reason why
you'd want to do that: you'll not be bitten when one of the
implementations contains a security bug, the chance that both at the same
time contain the same bug is slim.

Not that I know of.  The SSL tunnel is broken down though after use.

Not me, I don't trust google with my mail ;).
