In no particular order, and based on stuff I do myself.

*) DNS in auth and recursive, I always suggest keeping them in too separate "servers" (might be VMs) to ensure not opening up auth server for recursion etc.

*) Perhaps best current practice documents that even present BGP policies in general, like the old book "Cisco ISP Essentials (Cisco Press Networking Technology)[Paperback]" from 2002 available in free and open format would be great for getting more secure and robust networking.
Having examples in some popular variants would be great Juniper, Cisco, BIRD, OpenBGPD
- I also myself used the cymru web site a lot for similar stuff, http://www.team-cymru.org/ReadingRoom/Templates/

*) a small subject I would like see also is ICMP filtering.
We want people to know that blocking all of ICMP is bad for them and the internet. It prevents PMTU from working and is required for a lot of testing.

So maybe some re-iteration of the ICMP and presenting also the pingable attribute in whois?
(I dont use pingable myself yet, but perhaps receiving a nice BCOP doc would make me add some)

I wonder if testing is also part of this?

*) How to test your network performance, recommending some starting point for common testing inside networks, in my end of the world it seems to be iperf and smokeping that rules the land. I was pretty inspired by Jen Linkova at the RIPE65 meeting talking about creating stacked packet for testing MPLS
