I think you misunderstand how this works. Daemons do not run constantly in
the manner you appear to think. If you run "top" in a terminal you will
see that most processes at any given time are "sleeping". 

For example, currently on my machine I have

Tasks:  94 total,   2 running,  92 sleeping,   0 stopped,   0 zombie

The fact that a process is "listed" does not mean that it is running in
the sense that it is gobbling resources - just that it is "ready to run".
If you check the %CPU and %MEM columns in "top" you will see that most of
the things you are so concerned about are using minuscule resources, most
of the time.

Umm... no. There is (thank goodness) , no Linux equivalent to ActiveX.

Nothing can be activated remotely on an Ubuntu machine by default, because
no servers run by default. Nothing is listening. If you install servers,
then you decide the policy according to which you want those services to
be accessible.

Not by default, and only by the use of public/private keypairs. Since you
control that, the risk of passwordless login that you fear is non-existent.
SSH is precisely for the purpose of safe, encrypted communication.
Passwordless login can only be achieved if configured, and as I said
above, only by using keypairs. You have nothing to worry about. If you
want to stop sshd listening on the internet interface, any simple firewall
like, for example, "Firestarter" can be easily configured to drop port 22.
If you use a router you can configure that to block/drop connections as
well. Unless you have installed openssh-server, you only have the client
for ssh anyway, so this is a non-issue in a default Ubuntu install.

I think you are being fearful for no reason, and over-concerned about
the processes you name, based on a misunderstanding of the way the OS
actually works.
