Virtualization - when is it too much?

For a few years I have run vmware on top of a Linux install. Have worked just fine.
I have now an upgraded system with better performing hardware and would like to
play around some more with virtualiazation. I have just got a hi perf SSD added and
have a raid 0 stack for storage. I am picturing running even freeNAS as host.
Ultimate goal is of course easy to restore if something fails, just restart host.
Also I will try to get a more secure system, what do I do regarding firewall etc? I have 1 extra pc I could use for firewall, router etc. I would prefer though to run as much as possible as guest os.

Host OS really light Linux, might not even need GUI.
Then several guest OS. One guest for each task is the plan. Would be nice with "one box does it all".

*windows install normal use
*windows install SAFE use
*Linux normal use, GUI

I'll realize this might not be everyones cup of tea. And many might find this strange or over the top.
Nevertheless I belive it will be a good learning experiance and I will try to get the most out of the system.

For security what do I need? (firewall + + +?)
I have two GB lan connections and a 4 port GB switch, so if needed I can use one older pc for router, firewall etc.
How do I automate back up of system on to external NAS?

I will try to ellaborate a little.

I will need to run:

*Webserver
*Databases
*NAS
*Several (2 or 3) OS

How many guest OS can run simoultanously without notciable performance penalty? Really lightweight Host OS preferrable without GUI.

How can i set this up also considering wear levelling and making sure SSD performance do not degrade too much over time? I mean linux kernel now support Trim, right?

Ok tks man. Will look elsewhere for more help.
Regarding CPU strain I belive singel 6 core will work just fine, also I now run 16GB ram. After all not all VM's will run at full load 24/7. So I belive the hw is up for the task, it will be the setup that will either make or break this.

Btw. This is also a learning project as much as it is to tidy up all them boxes scattered around the house. Also when I now start this I will make sure to include automated backup as I before seldom did backups. A resent raid feilure have sure thought me a lesson and now I will test my limits and learn alot along the way.
