Yes.  How do you plan to set up file systems and configure a network
if you don't install anything?    My suggestion is that you install
FreeBSD 6.2 and only move locally created files to it.   This is
presuming the image you want to duplicate is at lower than 6.2.

Anyway, you can use the fixit system from CD to create filesystems
and then to restore the dumps which would give you an identical
system on the new machine, including IP and hostname.  You should
then be able to turn off the old machine and boot the new one in
its place.   I would then modify the hostname and IP on the old
machine rather than make the new server have the different name
so those things that are looking to it as server do not need to
be changed.

As for setting up filesharing before installing a system, I can't
say.  I haven't used it.
