Regardless of whether you install the binary or compile the source
from Subversion, it gets the dports tree from the location configured
in sources.conf. By default that's fetched using rsync but you can
change it to a Subversion working copy if you want.

With the binary installer, /opt/local is the prefix. When you build
from source, /opt/local is the default prefix but you can select
another if you prefer. The distfiles and build directories are
beneath the prefix.

Yes; just check out the source, configure, make and sudo make
install. It will overwrite the relevant files in /opt/local. I've
done this before.

I've never had to blow away /opt/local and start over. I use sudo for
most port commands, because they complain about permissions if I
don't. I could chown various directories but so far I haven't bothered.
