Personal network config information sources?

Hi,

I'm just beginning to think about the configuration options for a new
wireless network at home. I have ~ 6 machines running win32/Linux/Mac
and security is important so probably looking at a SoHo-type of
setup. Types of things I'm looking for:
- Media server. Will be controlled via smartphone client software.
- I'm thinking about taking back control of my email as the amount
personal information accumulating at a public provider is not helping
me sleep. Any recommendations? Any experiences of doing so with
Virtual Private Servers as explained here http://www.linuxjournal.com/article/8337?
- Will secure with OpenVPN. Possibly put VPN server behind two NAT
routers in serial, is this needed or any better alternatives?

Any thoughts and/or links to books, articles or blogs that might help
would be much appreciated.

Tia
Chad
