When moving between Android Versions via CM Updates, do I need to flash new GApps (as per jarrodr above) or do the updates to GApps come with the CM update itself?
Also, does updating erase all apps and data? It's not clear here: http://wiki.cyanogenmod.org/w/Updating
If so, I take it I need to go through the Titanium Backup process again to get me back to where I was?
Yes you need to go through the whole process. I've paid for Titanium which makes the process a whole lot simpler because it will install everything without you needing to confirm each app. Get a good upgrade routine going and it's not such a schlep. It is once off per Android version.
Once you do that you can update to each nightly for that release without having to wipe anything. Just install via recovery.
