High Avilability: to what point?

I am requested to offer a solution with high availability: but to what extent should I go with my deployment configuration?
I already have two reverse proxy and load balancing servers in an active-passive cluster, an active-active cluster of 4 application servers deployed on two nodes each on its own physical machine. Now, I will need a messaging server and a database. Should I go and cluster those two also? Am I going to far?

What deployment topology did you use for your assignment?

In my opinion you need to ensure that there is no single point of failure, going by this JMS & database will also need to be clustered.
It is sorta covered in the JavaRanch Style Guide.
