In reference to your networking section, i'm currently reading a few books about networking in general, and also some aimed at the security side of networks. Pretty much all of the books cover the TCP/IP suite, and talk about protocols such as ICMP, DHCP, IGMP etc but i've found that they just give a short summary about these such protocols.
It's called TCP/IP Illustrated The Protocols.

I think stuff on methodology and tactics - Internet firewalls - defending against Ip spoofing - DOS attacks would be very worthwhile, don't get dated quickly and are important to a wide range a people.
