Still learning myself :-)

Yes

No, depending on which flash you use, you can
set the controller one the either 'control' or to 'Master'
When set to 'Master' it will contribute to the illimunation, as
'control' it will not (just uses pre-flashes to control the slave)
You can do that with The AF360FGZ, AF540FGZ and the
builtin flash of the *istD, you can NOT do that (yet) with
the builtin flash of the K10D!
You need TWO wireless flashes with the K10D for that,
one on the camera (control/master) and another one (slave)
I actually did some experimenting with that a few days ago,
nothing fancy, using the K10D with AF360FGZ attached and
the AF540FGZ as second wireless flash.

I have not fully mastered contrast-control stuff yet, but
both flashes allow compensation to be set on the
flash itself, so should be possible.
