In the system preferences, I've set all of them to "None" for the various applications, but I'm still seeing things like software updates and battery status there in pop-ups in the top-right corner of my screen.
Is there any way to just turn off all notifications?
I have just disabled checking for updates automatically from System Preferences:
I install updates manually from App Store or with sudo softwareupdate -ia.
I tried adding this command to the root's crontab (and not restarting after updates):
0 14 * * * /usr/sbin/softwareupdate -ia
I didn't have any issues at first, but after the 10.8.3 update, Safari started crashing on launch until I restarted. After that I changed -ia to -da so the command just downloads updates. softwareupdate does not include updates for App Store applications though.
To disable this you will need to go to the Notifications and uncheck Show notifications on lock screen. There is no global disable, so you will have to do this for each app. To get there:
That will removal all the notifications from your lock screen.

Do Not Disturb will mute all notifications. You can enable it by opening Notification Center by clicking on the NC icon in the menubar (or sliding in from the side of the trackpad with two fingers) and turning the switch on.
You can permanently set Do Not Disturb on by going to System Preferences → Notifications and setting the schedule to "00:00 to 23:59".
To remove Notification Center altogether, you can run the following Terminal commands:
