Yes, and yes :)

If you want to use ccs-settings then you will need to make an xml
file with the options in it.

Depends on who you ask ;)

The default is gconf, preferred depends on requirements and
taste.  I personally prefer ini because its much easier to just
edit a textfile than click click click (for me anyway).  If you use
ini or gconf then you will be able to set the options without the
xml file.

It was a hatchet job, I would not be too grateful ;)

Viewport placement could probably be added to the place plugin
and it would work well with the other placement modes.

I think winrules does this, otherwise place would be the
obvious plugin for it.

Try adjusting the timestep options, they generally affect
the springyness of action movements.  I think you need to
make the value smaller.

Those options look like they just set the server that compiz
is running on.  The COW option is now gone.  Do you use AIGLX?

I have not heard of any workarounds for the black window bug.
