I attended the HA class last fall.  Unless you've got a company paying  
to send you, I'd say don't bother.  It's way too expensive.

* You'll get a very general introduction to a few ways to do HA for  
MySQL.  You'll hear about drbd, but not actually set it up.  (BTW,  
this isn't really that hard.)
* You'll spend most of a day setting up MySQL Cluster, which is a  
niche product useful in only a handful of circumstances.  Basically,  
it's great if you need an extremely available hash table.  If you need  
a general purpose DBMS, MySQL Cluster is not a good idea.
* You won't get much of any information on performance tuning.  HA !=  
performance.
