> 1. Is there a recommended brand and version of Linux to use with vserver?

Slackware is my favorite Linux distribution, but so far I have installed
vserver on SuSE 7.3(another favorite) using the rpm install. I would
recommend that you use the Linux distribution that you feel most comfortable

How would you use FreeBSD?

As John said I would put all the vservers in a single partition.

Install, exactly, only the software you need to run your vserver. When I made
my vserver setup, I used the Slackware 8.0 tar balls to create a custom
filesystem. Pick out only the packages you need and untar them into a
directory and, presto, custom filesystem. Less packages mean fewer possible
security concerns. If users don't need to change the base system on the
vserver I would suggest making it immutable, too.

Each different instance of a particular program binding to a particular port
needs to be on its own IP address. It is entirely possible to run apache in
its own vserver and the programs users use to access their files(ftp, ssh,
etc) on another. When setting things up keep thinking, "How can I separate
my users from stuff I don't want them to mess up.". That is one of the
greatest powers of vservers.

If everyone is using the same IP, I would use Virtual Hosts.
