You mean 2.6.24.x right?

Only the install one needs to be root.  sudo works just as well/

The directory that contains the jack source.  You likely downloaded a
.tar.gz or .tar.bz2 file.  Did you run tar -xvf name_of_jack_source.tar.bz2

Does not matter.  I tend to keep all my stuff built from source in /usr/src

As an alternative to make install, you could use checkinstall.  This
will create a .deb file that you can install and uninstall with apt.

You may wish to have a look here:
