If you must "read up".. remove wallet from computer immediately!!

I guess everything is relative. For me, it was mostly about starting to use a safe VPN (that accepts bitcoins). I think I had most bases covered before that.
Checklist:
1. Filesystem encryption.
2. Password management.
3. Individually encrypted wallets.
4. Local firewall.
5. Cron virus scan.
6. Sane file permissions.
7. VPN (with failsafe switch).
8. Encrypted wallets stored on several locations.
Todo:
1. Paper backup in safe.
