It's easy to tell ssh not to prompt before adding the host to
known_hosts.  Just put the line

StrictHostKeyChecking no

into the file "config" in the folder ".ssh" under your home directory.
  Or, alternatively, add the option

-o StrictHostKeyChecking=no

to the command line that you're running.

But passing in a password is a much harder prospect.  ssh doesn't read
the password from standard input, but forces a read from the terminal,
so there's no way to pipe it in from another command or a file.  You
would need something like the Expect system, but that's not a very
easy thing to set up or use.

What is preventing you from installing an ssh key on these hosts so
that you can copy without a password prompt?

Not related to the particular issues you raised, but I would recommend
using rsync rather than scp.  It's a friendly way to copy many files,
as it will only send the bare minimum data over the network.  Useful
to update a copy by only sending the bits that have changed since the
last time, for instance.    You still need to authenticate to each
host, though.
