I am working on the translation, and have links to more
pages with a lot more detail to that.

Because TTL in all flavors renders different power output
with different position of your subject, and it only works
well with average subject contrast. To achieve strong
contrasts and modulate your subject precisely you need
fixed power output and a flash meter. TTL is not able to
do this without massive manipulation or nasty surprises.
So to make a very differentiated stunning light you will
need a flash meter anyway, and I highly recommend a handheld
meter for everyone striving to control his tonal range
on top of that. You can do with test shots on a D30, in
fact I rarely use my flash meter anymore.
Shoe mount flashes are not made for continuous use. You
will have a lot of hassle to always have fresh batteries.
Mains operated slaves save you from that.

No. You need a reproducable, calculatable output.
In camera metering is nice for flat lighting from
the camera, but it doesn't do much good elsewhere.

Because you lose control over what you are doing, and in
situations with high contrasts you can almost be sure that
the transmitter won't trigger the remote flash.
You might want to do slight adjustments and see what
the difference is. TTL metering will level most of
your sophisticated light. Precise, reproducable manual
settings preserve it.
