FWIW, there was a list of videos just posted to freebsd-fs a couple days 
ago. If you decide to jump into ZFS, after you have a handle on all the 
basics it might be worth watching these two videos:

An Introduction to the Implementation of ZFS (part 2 of 2):

understand the why and how of ZFS' more complex parts.
