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.
The thing I'm concerned about is keyloggers.
My password is very long and secure and I have it completely memorised, I only use it for things like Bitcoin and it's never been written down.
Due to the price of these coins I'm going to get a separate computer (probably a cheap netbook) to store my Bitcoin client on.
I'll use it only for doing transfers, nothing else.
Of course I have my wallets backed up in various places as well.
