It should start automatically.  Certainly for me it does.  I have the
following links in the /etc/rc*.d directories.  Note that I installed
apt-proxy while running breezy, and it was upgraded when I migrated to
dapper):
tim at marvin:~$ ls -l /etc/rc*.d/*apt-proxy
lrwxrwxrwx 1 root root 19 2005-12-12 22:18 /etc/rc0.d/K20apt-proxy
-> ../init.d/apt-proxy
lrwxrwxrwx 1 root root 19 2005-12-12 22:18 /etc/rc1.d/K20apt-proxy

lrwxrwxrwx 1 root root 19 2005-12-12 22:18 /etc/rc2.d/S20apt-proxy

lrwxrwxrwx 1 root root 19 2005-12-12 22:18 /etc/rc5.d/S20apt-proxy

lrwxrwxrwx 1 root root 19 2005-12-12 22:18 /etc/rc6.d/K20apt-proxy
-> ../init.d/apt-proxy

If those symlinks don't already exist, they can be created.  Make sure
that the start/stop script exists in /etc/init.d.

You should not need to change this from the default.

Since all the machines you are working with are ubuntu, then yes, you
can delete all the commented-out debian repositories.

You need a complete entry for each repository.  For instance, I have the
following for Seveas:
[ubuntu-seveas]
;; Dennis Kaarsemakers repository - mirror
backends = http://mirror2.ubuntulinux.nl/

The tag '[ubuntu-seveas]' labels the entry, and must be unique within
the apt-proxy configuration.  The name is used in the sources.list entry
for each PC that you set up to use apt-proxy.

You need to reference the entry that you added to apt-proxy-v2.conf.
So, for Seveas' repository, I have the following entry, on a machine
running edgy (marvin is the host running apt-proxy, and has been added
to /etc/hosts):
	deb http://marvin:9999/ubuntu-seveas edgy-seveas all
