Your questions cannot be answer specifically because they do not contain
enough info.  Here is what I chose to do in a similar but smaller enviro.

1.  This a good place for virtualization.  FreeBSD jails are the most
efficient form that I'm aware of including XEN.  Jails have limitations XEN
doesn't however.
2.  High load DB's shouldn't be virtualized.
3.  EZjails port helps alot!
4.  Machine specs would depend on system load, you've given no indication
other than apps.
5.  You should preplan backup and failover setup.  Heartbeat, CARP, rdiff,
and other utilities should help here.
